/*
    The goal of this version of close is different than that of sqlite3_close(), and is designed to lend itself better to .NET's non-deterministic finalizers and
    the GC thread.  SQLite will not close a database if statements are open on it -- but for our purposes, we'd rather finalize all active statements
    and forcibly close the database.  The reason is simple -- a lot of people don't Dispose() of their objects correctly and let the garbage collector
    do it.  This leads to unexpected behavior when a user thinks they've closed a database, but it's still open because not all the statements have
    hit the GC yet.

/*
    The goal of this version of close is different than that of sqlite3_close(), and is designed to lend itself better to .NET's non-deterministic finalizers and
    the GC thread.  SQLite will not close a database if statements are open on it -- but for our purposes, we'd rather finalize all active statements
    and forcibly close the database.  The reason is simple -- a lot of people don't Dispose() of their objects correctly and let the garbage collector
    do it.  This leads to unexpected behavior when a user thinks they've closed a database, but it's still open because not all the statements have
    hit the GC yet.

** This file is an amalgamation of many separate C source files from SQLite

** possible if the files were compiled separately.  Performance improvements
** of 5% are more are commonly seen when SQLite is compiled as a single
** translation unit.
**
** This file is all you need to compile SQLite.  To use SQLite in other
** programs, you need this file and the "sqlite3.h" header file that defines
** the programming interface to the SQLite library.  (If you do not have 
** the "sqlite3.h" header file at hand, you will find a copy in the first
** 6312 lines past this header comment.)  Additional code files may be
** needed if you want a wrapper to interface SQLite with your choice of
** programming language.  The code for the "sqlite3" command-line shell
** is also in a separate file.  This file contains only code for the core
** SQLite library.

**
** SQLite can be compiled with or without mutexes.  When
** the [SQLITE_THREADSAFE] C preprocessor macro is true, mutexes
** are enabled and SQLite is threadsafe.  When that macro is false,

** the mutexes are omitted.  Without the mutexes, it is not safe
** to use SQLite concurrently from more than one thread.
**
** Enabling mutexes incurs a measurable performance penalty.
** So if speed is of utmost importance, it makes sense to disable
** the mutexes.  But for maximum safety, mutexes should be enabled.
** The default behavior is for mutexes to be enabled.
................................................................................
** SQLITE_THREADSAFE=1 then mutexes are enabled by default but
** can be fully or partially disabled using a call to [sqlite3_config()]
** with the verbs [SQLITE_CONFIG_SINGLETHREAD], [SQLITE_CONFIG_MULTITHREAD],
** or [SQLITE_CONFIG_MUTEX].  The return value of this function shows
** only the default compile-time setting, not any run-time changes
** to that setting.
**


** INVARIANTS:
**
** {H10101} The [sqlite3_threadsafe()] function shall return nonzero if

**          SQLite was compiled with the its mutexes enabled by default
**          or zero if SQLite was compiled such that mutexes are
**          permanently disabled.
**
** {H10102} The value returned by the [sqlite3_threadsafe()] function
**          shall not change when mutex setting are modified at

** <dt>SQLITE_CONFIG_MULTITHREAD</dt>
** <dd>There are no arguments to this option.  This option disables
** mutexing on [database connection] and [prepared statement] objects.
** The application is responsible for serializing access to
** [database connections] and [prepared statements].  But other mutexes
** are enabled so that SQLite will be safe to use in a multi-threaded
** environment.</dd>


**
** <dt>SQLITE_CONFIG_SERIALIZED</dt>
** <dd>There are no arguments to this option.  This option enables
** all mutexes including the recursive
** mutexes on [database connection] and [prepared statement] objects.
** In this mode (which is the default when SQLite is compiled with
** [SQLITE_THREADSAFE=1]) the SQLite library will itself serialize access
** to [database connections] and [prepared statements] so that the
** application is free to use the same [database connection] or the
** same [prepared statement] in different threads at the same time.
**
** <p>This configuration option merely sets the default mutex 
** behavior to serialize access to [database connections].  Individual
** [database connections] can override this setting
** using the [SQLITE_OPEN_NOMUTEX] flag to [sqlite3_open_v2()].</p></dd>
**
** <dt>SQLITE_CONFIG_MALLOC</dt>
** <dd>This option takes a single argument which is a pointer to an

**
................................................................................
** this is important.
**
** There can only be a single busy handler defined for each
** [database connection].  Setting a new busy handler clears any
** previously set handler.  Note that calling [sqlite3_busy_timeout()]
** will also set or clear the busy handler.
**




** INVARIANTS:
**
** {H12311} The [sqlite3_busy_handler(D,C,A)] function shall replace
**          busy callback in the [database connection] D with a new

** Only a single authorizer can be in place on a database connection
** at a time.  Each call to sqlite3_set_authorizer overrides the
** previous call.  Disable the authorizer by installing a NULL callback.
** The authorizer is disabled by default.
**





** When [sqlite3_prepare_v2()] is used to prepare a statement, the
** statement might be reprepared during [sqlite3_step()] due to a 
** schema change.  Hence, the application should ensure that the
** correct authorizer callback remains in place during the [sqlite3_step()].

** interface is to keep a GUI updated during a large query.
**
** If the progress callback returns non-zero, the operation is

** associated with the [database connection] handle should be released by
** passing it to [sqlite3_close()] when it is no longer required.
**
** The sqlite3_open_v2() interface works like sqlite3_open()
** except that it accepts two additional parameters for additional control
** over the new database connection.  The flags parameter can take one of
** the following three values, optionally combined with the 
** [SQLITE_OPEN_NOMUTEX] flag:
**
** <dl>
** <dt>[SQLITE_OPEN_READONLY]</dt>
** <dd>The database is opened in read-only mode.  If the database does not
** already exist, an error is returned.</dd>
**
** <dt>[SQLITE_OPEN_READWRITE]</dt>
................................................................................
** <dd>The database is opened for reading and writing, and is creates it if
** it does not already exist. This is the behavior that is always used for
** sqlite3_open() and sqlite3_open16().</dd>
** </dl>
**
** If the 3rd parameter to sqlite3_open_v2() is not one of the
** combinations shown above or one of the combinations shown above combined

** with the [SQLITE_OPEN_NOMUTEX] flag, then the behavior is undefined.
**
** If the [SQLITE_OPEN_NOMUTEX] flag is set, then mutexes on the
** opened [database connection] are disabled and the appliation must
** insure that access to the [database connection] and its associated
** [prepared statements] is serialized.  The [SQLITE_OPEN_NOMUTEX] flag
** is the default behavior is SQLite is configured using the
** [SQLITE_CONFIG_MULTITHREAD] or [SQLITE_CONFIG_SINGLETHREAD] options
** to [sqlite3_config()].  The [SQLITE_OPEN_NOMUTEX] flag only makes a
** difference when SQLite is in its default [SQLITE_CONFIG_SERIALIZED] mode.
**
** If the filename is ":memory:", then a private, temporary in-memory database
** is created for the connection.  This in-memory database will vanish when
** the database connection is closed.  Future versions of SQLite might
** make use of additional special filenames that begin with the ":" character.
** It is recommended that when a database filename actually does begin with
** a ":" character you should prefix the filename with a pathname such as
................................................................................
**
** The second parameter is the name of the SQL function to be created or
** redefined.  The length of the name is limited to 255 bytes, exclusive of
** the zero-terminator.  Note that the name length limit is in bytes, not
** characters.  Any attempt to create a function with a longer name
** will result in [SQLITE_ERROR] being returned.
**

** The third parameter is the number of arguments that the SQL function or
** aggregate takes. If this parameter is negative, then the SQL function or
** aggregate may take any number of arguments.
**
** The fourth parameter, eTextRep, specifies what
** [SQLITE_UTF8 | text encoding] this SQL function prefers for
** its parameters.  Any SQL function implementation should be able to work
** work with UTF-8, UTF-16le, or UTF-16be.  But some implementations may be
................................................................................
** and xFinal and NULL should be passed for xFunc. To delete an existing
** SQL function or aggregate, pass NULL for all three function callbacks.
**
** It is permitted to register multiple implementations of the same
** functions with the same name but with either differing numbers of
** arguments or differing preferred text encodings.  SQLite will use
** the implementation most closely matches the way in which the
** SQL function is used.







**












** INVARIANTS:
**
** {H16103} The [sqlite3_create_function16()] interface behaves exactly
**          like [sqlite3_create_function()] in every way except that it
**          interprets the zFunctionName argument as zero-terminated UTF-16
**          native byte order instead of as zero-terminated UTF-8.
**
** {H16106} A successful invocation of
**          the [sqlite3_create_function(D,X,N,E,...)] interface registers
**          or replaces callback functions in the [database connection] D
**          used to implement the SQL function named X with N parameters

** {H16109} A successful call to [sqlite3_create_function(D,X,N,E,P,F,S,L)]
**          replaces the P, F, S, and L values from any prior calls with
**          the same D, X, N, and E values.
**
** {H16112} The [sqlite3_create_function(D,X,...)] interface fails with
**          a return code of [SQLITE_ERROR] if the SQL function name X is
**          longer than 255 bytes exclusive of the zero terminator.

** {H16121} The [sqlite3_create_function(D,...)] interface fails with an
**          error code of [SQLITE_BUSY] if there exist [prepared statements]
**          associated with the [database connection] D.
**
** {H16124} The [sqlite3_create_function(D,X,N,...)] interface fails with an
**          error code of [SQLITE_ERROR] if parameter N (specifying the number
**          of arguments to the SQL function being registered) is less
**          than -1 or greater than 127.
**
** {H16127} When N is non-negative, the [sqlite3_create_function(D,X,N,...)]
**          interface causes callbacks to be invoked for the SQL function

**          named X when the number of arguments to the SQL function is
**          exactly N.
**
** {H16130} When N is -1, the [sqlite3_create_function(D,X,N,...)]
**          interface causes callbacks to be invoked for the SQL function
**          named X with any number of arguments.
**
** {H16133} When calls to [sqlite3_create_function(D,X,N,...)]
**          specify multiple implementations of the same function X
**          and when one implementation has N>=0 and the other has N=(-1)
**          the implementation with a non-zero N is preferred.
**
** {H16136} When calls to [sqlite3_create_function(D,X,N,E,...)]
**          specify multiple implementations of the same function X with
**          the same number of arguments N but with different
**          encodings E, then the implementation where E matches the
**          database encoding is preferred.
**
** {H16139} For an aggregate SQL function created using
**          [sqlite3_create_function(D,X,N,E,P,0,S,L)] the finalizer
**          function L will always be invoked exactly once if the
**          step function S is called one or more times.
**
** {H16142} When SQLite invokes either the xFunc or xStep function of
**          an application-defined SQL function or aggregate created
**          by [sqlite3_create_function()] or [sqlite3_create_function16()],
**          then the array of [sqlite3_value] objects passed as the

/******************************************************************************
** This file is an amalgamation of many separate C source files from SQLite
** version 3.6.3.  By combining all the individual C code files into this 
** single large file, the entire code can be compiled as a one translation
** unit.  This allows many compilers to do optimizations that would not be
** possible if the files were compiled separately.  Performance improvements
** of 5% are more are commonly seen when SQLite is compiled as a single
** translation unit.
**
** This file is all you need to compile SQLite.  To use SQLite in other
** programs, you need this file and the "sqlite3.h" header file that defines
** the programming interface to the SQLite library.  (If you do not have 
** the "sqlite3.h" header file at hand, you will find a copy in the first
** 6364 lines past this header comment.)  Additional code files may be
** needed if you want a wrapper to interface SQLite with your choice of
** programming language.  The code for the "sqlite3" command-line shell
** is also in a separate file.  This file contains only code for the core
** SQLite library.

** SQLite can be compiled with or without mutexes.  When
** the [SQLITE_THREADSAFE] C preprocessor macro 1 or 2, mutexes
** are enabled and SQLite is threadsafe.  When the
** [SQLITE_THREADSAFE] macro is 0, 
** the mutexes are omitted.  Without the mutexes, it is not safe
** to use SQLite concurrently from more than one thread.
**
** Enabling mutexes incurs a measurable performance penalty.

** the mutexes.  But for maximum safety, mutexes should be enabled.
** The default behavior is for mutexes to be enabled.
................................................................................

** can be fully or partially disabled using a call to [sqlite3_config()]
** with the verbs [SQLITE_CONFIG_SINGLETHREAD], [SQLITE_CONFIG_MULTITHREAD],

** only the default compile-time setting, not any run-time changes
** to that setting.

** <dt>SQLITE_CONFIG_MALLOC</dt>
** <dd>This option takes a single argument which is a pointer to an

**
** There can only be a single busy handler defined for each
** [database connection].  Setting a new busy handler clears any

** will also set or clear the busy handler.
**
** The busy callback should not take any actions which modify the
** database connection that invoked the busy handler.  Any such actions
** result in undefined behavior.
** 
** INVARIANTS:
**
** {H12311} The [sqlite3_busy_handler(D,C,A)] function shall replace
**          busy callback in the [database connection] D with a new

**
** Only a single authorizer can be in place on a database connection
** at a time.  Each call to sqlite3_set_authorizer overrides the
** previous call.  Disable the authorizer by installing a NULL callback.
** The authorizer is disabled by default.
**
** The authorizer callback must not do anything that will modify
** the database connection that invoked the authorizer callback.
** Note that [sqlite3_prepare_v2()] and [sqlite3_step()] both modify their
** database connections for the meaning of "modify" in this paragraph.
**
** When [sqlite3_prepare_v2()] is used to prepare a statement, the
** statement might be reprepared during [sqlite3_step()] due to a 
** schema change.  Hence, the application should ensure that the
** correct authorizer callback remains in place during the [sqlite3_step()].

** Note that the authorizer callback is invoked only during

** progress callback - that is invoked periodically during long
** running calls to [sqlite3_exec()], [sqlite3_step()] and
** [sqlite3_get_table()].  An example use for this
** interface is to keep a GUI updated during a large query.
**
** If the progress callback returns non-zero, the operation is
** interrupted.  This feature can be used to implement a
** "Cancel" button on a GUI progress dialog box.
**
** The progress handler must not do anything that will modify
** the database connection that invoked the progress handler.
** Note that [sqlite3_prepare_v2()] and [sqlite3_step()] both modify their
** database connections for the meaning of "modify" in this paragraph.
**
** INVARIANTS:

................................................................................
** associated with the [database connection] handle should be released by
** passing it to [sqlite3_close()] when it is no longer required.
**
** The sqlite3_open_v2() interface works like sqlite3_open()
** except that it accepts two additional parameters for additional control
** over the new database connection.  The flags parameter can take one of
** the following three values, optionally combined with the 
** [SQLITE_OPEN_NOMUTEX] or [SQLITE_OPEN_FULLMUTEX] flags:
**
** <dl>
** <dt>[SQLITE_OPEN_READONLY]</dt>
** <dd>The database is opened in read-only mode.  If the database does not
** already exist, an error is returned.</dd>
**
** <dt>[SQLITE_OPEN_READWRITE]</dt>
................................................................................
** <dd>The database is opened for reading and writing, and is creates it if
** it does not already exist. This is the behavior that is always used for
** sqlite3_open() and sqlite3_open16().</dd>
** </dl>
**
** If the 3rd parameter to sqlite3_open_v2() is not one of the
** combinations shown above or one of the combinations shown above combined
** with the [SQLITE_OPEN_NOMUTEX] or [SQLITE_OPEN_FULLMUTEX] flags,
** then the behavior is undefined.
**
** If the [SQLITE_OPEN_NOMUTEX] flag is set, then the database connection

** opens in the multi-thread [threading mode] as long as the single-thread
** mode has not been set at compile-time or start-time.  If the
** [SQLITE_OPEN_FULLMUTEX] flag is set then the database connection opens
** in the serialized [threading mode] unless single-thread was
** previously selected at compile-time or start-time.

**
** If the filename is ":memory:", then a private, temporary in-memory database
** is created for the connection.  This in-memory database will vanish when
** the database connection is closed.  Future versions of SQLite might
** make use of additional special filenames that begin with the ":" character.
** It is recommended that when a database filename actually does begin with
** a ":" character you should prefix the filename with a pathname such as
................................................................................
**
** The second parameter is the name of the SQL function to be created or
** redefined.  The length of the name is limited to 255 bytes, exclusive of
** the zero-terminator.  Note that the name length limit is in bytes, not
** characters.  Any attempt to create a function with a longer name
** will result in [SQLITE_ERROR] being returned.
**
** The third parameter (nArg)
** is the number of arguments that the SQL function or
** aggregate takes. If this parameter is negative, then the SQL function or
** aggregate may take any number of arguments.
**
** The fourth parameter, eTextRep, specifies what
** [SQLITE_UTF8 | text encoding] this SQL function prefers for
** its parameters.  Any SQL function implementation should be able to work
** work with UTF-8, UTF-16le, or UTF-16be.  But some implementations may be
................................................................................
** and xFinal and NULL should be passed for xFunc. To delete an existing
** SQL function or aggregate, pass NULL for all three function callbacks.
**
** It is permitted to register multiple implementations of the same
** functions with the same name but with either differing numbers of
** arguments or differing preferred text encodings.  SQLite will use
** the implementation most closely matches the way in which the
** SQL function is used.  A function implementation with a non-negative
** nArg parameter is a better match than a function implementation with
** a negative nArg.  A function where the preferred text encoding
** matches the database encoding is a better
** match than a function where the encoding is different.  
** A function where the encoding difference is between UTF16le and UTF16be
** is a closer match than a function where the encoding difference is
** between UTF8 and UTF16.
**
** Built-in functions may be overloaded by new application-defined functions.
** The first application-defined function with a given name overrides all
** built-in functions in the same [database connection] with the same name.
** Subsequent application-defined functions of the same name only override 
** prior application-defined functions that are an exact match for the
** number of parameters and preferred encoding.
**
** An application-defined function is permitted to call other
** SQLite interfaces.  However, such calls must not
** close the database connection nor finalize or reset the prepared
** statement in which the function is running.
**
** INVARIANTS:
**
** {H16103} The [sqlite3_create_function16(D,X,...)] interface shall behave
**          as [sqlite3_create_function(D,X,...)] in every way except that it

**
** {H16106} A successful invocation of the

**
** {H16112} The [sqlite3_create_function(D,X,...)] interface shall fail
**          if the SQL function name X is

**
** {H16118} The [sqlite3_create_function(D,X,N,E,P,F,S,L)] interface

**
** {H16121} The [sqlite3_create_function(D,...)] interface shall fails with an

**          associated with the [database connection] D.
**
** {H16124} The [sqlite3_create_function(D,X,N,...)] interface shall fail with
**          an error code of [SQLITE_ERROR] if parameter N is less

**          than -1 or greater than 127.
**
** {H16127} When N is non-negative, the [sqlite3_create_function(D,X,N,...)]
**          interface shall register callbacks to be invoked for the
**          SQL function
**          named X when the number of arguments to the SQL function is
**          exactly N.
**
** {H16130} When N is -1, the [sqlite3_create_function(D,X,N,...)]
**          interface shall register callbacks to be invoked for the SQL
**          function named X with any number of arguments.
**
** {H16133} When calls to [sqlite3_create_function(D,X,N,...)]
**          specify multiple implementations of the same function X
**          and when one implementation has N>=0 and the other has N=(-1)
**          the implementation with a non-zero N shall be preferred.
**
** {H16136} When calls to [sqlite3_create_function(D,X,N,E,...)]
**          specify multiple implementations of the same function X with
**          the same number of arguments N but with different

**          an application-defined SQL function or aggregate created
**          by [sqlite3_create_function()] or [sqlite3_create_function16()],

**
** SQLite can be compiled with or without mutexes.  When
** the [SQLITE_THREADSAFE] C preprocessor macro is true, mutexes
** are enabled and SQLite is threadsafe.  When that macro is false,

** the mutexes are omitted.  Without the mutexes, it is not safe
** to use SQLite concurrently from more than one thread.
**
** Enabling mutexes incurs a measurable performance penalty.
** So if speed is of utmost importance, it makes sense to disable
** the mutexes.  But for maximum safety, mutexes should be enabled.
** The default behavior is for mutexes to be enabled.
................................................................................
** SQLITE_THREADSAFE=1 then mutexes are enabled by default but
** can be fully or partially disabled using a call to [sqlite3_config()]
** with the verbs [SQLITE_CONFIG_SINGLETHREAD], [SQLITE_CONFIG_MULTITHREAD],
** or [SQLITE_CONFIG_MUTEX].  The return value of this function shows
** only the default compile-time setting, not any run-time changes
** to that setting.
**


** INVARIANTS:
**
** {H10101} The [sqlite3_threadsafe()] function shall return nonzero if

**          SQLite was compiled with the its mutexes enabled by default
**          or zero if SQLite was compiled such that mutexes are
**          permanently disabled.
**
** {H10102} The value returned by the [sqlite3_threadsafe()] function
**          shall not change when mutex setting are modified at
**          runtime using the [sqlite3_config()] interface and 
**          especially the [SQLITE_CONFIG_SINGLETHREAD],
**          [SQLITE_CONFIG_MULTITHREAD], [SQLITE_CONFIG_SERIALIZED],
**          and [SQLITE_CONFIG_MUTEX] verbs.
................................................................................
**
** <dt>SQLITE_CONFIG_MULTITHREAD</dt>
** <dd>There are no arguments to this option.  This option disables
** mutexing on [database connection] and [prepared statement] objects.
** The application is responsible for serializing access to
** [database connections] and [prepared statements].  But other mutexes
** are enabled so that SQLite will be safe to use in a multi-threaded
** environment.</dd>


**
** <dt>SQLITE_CONFIG_SERIALIZED</dt>
** <dd>There are no arguments to this option.  This option enables
** all mutexes including the recursive
** mutexes on [database connection] and [prepared statement] objects.
** In this mode (which is the default when SQLite is compiled with
** [SQLITE_THREADSAFE=1]) the SQLite library will itself serialize access
** to [database connections] and [prepared statements] so that the
** application is free to use the same [database connection] or the
** same [prepared statement] in different threads at the same time.
**
** <p>This configuration option merely sets the default mutex 
** behavior to serialize access to [database connections].  Individual
** [database connections] can override this setting
** using the [SQLITE_OPEN_NOMUTEX] flag to [sqlite3_open_v2()].</p></dd>
**
** <dt>SQLITE_CONFIG_MALLOC</dt>
** <dd>This option takes a single argument which is a pointer to an
** instance of the [sqlite3_mem_methods] structure.  The argument specifies
** alternative low-level memory allocation routines to be used in place of

**
................................................................................
** this is important.
**
** There can only be a single busy handler defined for each
** [database connection].  Setting a new busy handler clears any
** previously set handler.  Note that calling [sqlite3_busy_timeout()]
** will also set or clear the busy handler.
**




** INVARIANTS:
**
** {H12311} The [sqlite3_busy_handler(D,C,A)] function shall replace
**          busy callback in the [database connection] D with a new
**          a new busy handler C and application data pointer A.

**
** Only a single authorizer can be in place on a database connection
** at a time.  Each call to sqlite3_set_authorizer overrides the
** previous call.  Disable the authorizer by installing a NULL callback.
** The authorizer is disabled by default.
**





** When [sqlite3_prepare_v2()] is used to prepare a statement, the
** statement might be reprepared during [sqlite3_step()] due to a 
** schema change.  Hence, the application should ensure that the
** correct authorizer callback remains in place during the [sqlite3_step()].
**
** Note that the authorizer callback is invoked only during
** [sqlite3_prepare()] or its variants.  Authorization is not

** progress callback - that is invoked periodically during long
** running calls to [sqlite3_exec()], [sqlite3_step()] and
** [sqlite3_get_table()].  An example use for this
** interface is to keep a GUI updated during a large query.
**
** If the progress callback returns non-zero, the operation is
** interrupted.  This feature can be used to implement a
** "Cancel" button on a GUI dialog box.





**
** INVARIANTS:
**
** {H12911} The callback function registered by sqlite3_progress_handler()

................................................................................
** associated with the [database connection] handle should be released by
** passing it to [sqlite3_close()] when it is no longer required.
**
** The sqlite3_open_v2() interface works like sqlite3_open()
** except that it accepts two additional parameters for additional control
** over the new database connection.  The flags parameter can take one of
** the following three values, optionally combined with the 
** [SQLITE_OPEN_NOMUTEX] flag:
**
** <dl>
** <dt>[SQLITE_OPEN_READONLY]</dt>
** <dd>The database is opened in read-only mode.  If the database does not
** already exist, an error is returned.</dd>
**
** <dt>[SQLITE_OPEN_READWRITE]</dt>
................................................................................
** <dd>The database is opened for reading and writing, and is creates it if
** it does not already exist. This is the behavior that is always used for
** sqlite3_open() and sqlite3_open16().</dd>
** </dl>
**
** If the 3rd parameter to sqlite3_open_v2() is not one of the
** combinations shown above or one of the combinations shown above combined

** with the [SQLITE_OPEN_NOMUTEX] flag, then the behavior is undefined.
**
** If the [SQLITE_OPEN_NOMUTEX] flag is set, then mutexes on the
** opened [database connection] are disabled and the appliation must
** insure that access to the [database connection] and its associated
** [prepared statements] is serialized.  The [SQLITE_OPEN_NOMUTEX] flag
** is the default behavior is SQLite is configured using the
** [SQLITE_CONFIG_MULTITHREAD] or [SQLITE_CONFIG_SINGLETHREAD] options
** to [sqlite3_config()].  The [SQLITE_OPEN_NOMUTEX] flag only makes a
** difference when SQLite is in its default [SQLITE_CONFIG_SERIALIZED] mode.
**
** If the filename is ":memory:", then a private, temporary in-memory database
** is created for the connection.  This in-memory database will vanish when
** the database connection is closed.  Future versions of SQLite might
** make use of additional special filenames that begin with the ":" character.
** It is recommended that when a database filename actually does begin with
** a ":" character you should prefix the filename with a pathname such as
................................................................................
**
** The second parameter is the name of the SQL function to be created or
** redefined.  The length of the name is limited to 255 bytes, exclusive of
** the zero-terminator.  Note that the name length limit is in bytes, not
** characters.  Any attempt to create a function with a longer name
** will result in [SQLITE_ERROR] being returned.
**

** The third parameter is the number of arguments that the SQL function or
** aggregate takes. If this parameter is negative, then the SQL function or
** aggregate may take any number of arguments.
**
** The fourth parameter, eTextRep, specifies what
** [SQLITE_UTF8 | text encoding] this SQL function prefers for
** its parameters.  Any SQL function implementation should be able to work
** work with UTF-8, UTF-16le, or UTF-16be.  But some implementations may be
................................................................................
** and xFinal and NULL should be passed for xFunc. To delete an existing
** SQL function or aggregate, pass NULL for all three function callbacks.
**
** It is permitted to register multiple implementations of the same
** functions with the same name but with either differing numbers of
** arguments or differing preferred text encodings.  SQLite will use
** the implementation most closely matches the way in which the
** SQL function is used.







**












** INVARIANTS:
**
** {H16103} The [sqlite3_create_function16()] interface behaves exactly
**          like [sqlite3_create_function()] in every way except that it
**          interprets the zFunctionName argument as zero-terminated UTF-16
**          native byte order instead of as zero-terminated UTF-8.
**
** {H16106} A successful invocation of
**          the [sqlite3_create_function(D,X,N,E,...)] interface registers

**
** Enabling mutexes incurs a measurable performance penalty.

** The sqlite3_open_v2() interface works like sqlite3_open()
** except that it accepts two additional parameters for additional control

** combinations shown above or one of the combinations shown above combined

** then the behavior is undefined.
**
** If the [SQLITE_OPEN_NOMUTEX] flag is set, then the database connection

** opens in the multi-thread [threading mode] as long as the single-thread
** mode has not been set at compile-time or start-time.  If the
** [SQLITE_OPEN_FULLMUTEX] flag is set then the database connection opens
** in the serialized [threading mode] unless single-thread was
** previously selected at compile-time or start-time.

**
** If the filename is ":memory:", then a private, temporary in-memory database
** is created for the connection.  This in-memory database will vanish when
** the database connection is closed.  Future versions of SQLite might
** make use of additional special filenames that begin with the ":" character.
** It is recommended that when a database filename actually does begin with
** a ":" character you should prefix the filename with a pathname such as
................................................................................
**
** The second parameter is the name of the SQL function to be created or
** redefined.  The length of the name is limited to 255 bytes, exclusive of
** the zero-terminator.  Note that the name length limit is in bytes, not
** characters.  Any attempt to create a function with a longer name
** will result in [SQLITE_ERROR] being returned.
**
** The third parameter (nArg)
** is the number of arguments that the SQL function or
** aggregate takes. If this parameter is negative, then the SQL function or
** aggregate may take any number of arguments.
**
** The fourth parameter, eTextRep, specifies what
** [SQLITE_UTF8 | text encoding] this SQL function prefers for
** its parameters.  Any SQL function implementation should be able to work
** work with UTF-8, UTF-16le, or UTF-16be.  But some implementations may be
................................................................................
** and xFinal and NULL should be passed for xFunc. To delete an existing
** SQL function or aggregate, pass NULL for all three function callbacks.
**
** It is permitted to register multiple implementations of the same
** functions with the same name but with either differing numbers of
** arguments or differing preferred text encodings.  SQLite will use
** the implementation most closely matches the way in which the
** SQL function is used.  A function implementation with a non-negative
** nArg parameter is a better match than a function implementation with
** a negative nArg.  A function where the preferred text encoding
** matches the database encoding is a better
** match than a function where the encoding is different.  
** A function where the encoding difference is between UTF16le and UTF16be
** is a closer match than a function where the encoding difference is
** between UTF8 and UTF16.
**
** Built-in functions may be overloaded by new application-defined functions.
** The first application-defined function with a given name overrides all
** built-in functions in the same [database connection] with the same name.
** Subsequent application-defined functions of the same name only override 
** prior application-defined functions that are an exact match for the
** number of parameters and preferred encoding.
**
** An application-defined function is permitted to call other
** SQLite interfaces.  However, such calls must not
** close the database connection nor finalize or reset the prepared
** statement in which the function is running.
**
** INVARIANTS:
**
** {H16103} The [sqlite3_create_function16(D,X,...)] interface shall behave
**          as [sqlite3_create_function(D,X,...)] in every way except that it
**          interprets the X argument as zero-terminated UTF-16
**          native byte order instead of as zero-terminated UTF-8.
**
** {H16106} A successful invocation of the
**          [sqlite3_create_function(D,X,N,E,...)] interface shall register
**          or replaces callback functions in the [database connection] D
**          used to implement the SQL function named X with N parameters
**          and having a preferred text encoding of E.
**
** {H16109} A successful call to [sqlite3_create_function(D,X,N,E,P,F,S,L)]
**          shall replace the P, F, S, and L values from any prior calls with
**          the same D, X, N, and E values.
**
** {H16112} The [sqlite3_create_function(D,X,...)] interface shall fail
**          if the SQL function name X is
**          longer than 255 bytes exclusive of the zero terminator.
**
** {H16118} The [sqlite3_create_function(D,X,N,E,P,F,S,L)] interface
**          shall fail unless either F is NULL and S and L are non-NULL or
***         F is non-NULL and S and L are NULL.

**
** {H16121} The [sqlite3_create_function(D,...)] interface shall fails with an
**          error code of [SQLITE_BUSY] if there exist [prepared statements]
**          associated with the [database connection] D.
**
** {H16124} The [sqlite3_create_function(D,X,N,...)] interface shall fail with
**          an error code of [SQLITE_ERROR] if parameter N is less

**          than -1 or greater than 127.
**
** {H16127} When N is non-negative, the [sqlite3_create_function(D,X,N,...)]
**          interface shall register callbacks to be invoked for the
**          SQL function
**          named X when the number of arguments to the SQL function is
**          exactly N.
**
** {H16130} When N is -1, the [sqlite3_create_function(D,X,N,...)]
**          interface shall register callbacks to be invoked for the SQL
**          function named X with any number of arguments.
**
** {H16133} When calls to [sqlite3_create_function(D,X,N,...)]
**          specify multiple implementations of the same function X
**          and when one implementation has N>=0 and the other has N=(-1)
**          the implementation with a non-zero N shall be preferred.
**
** {H16136} When calls to [sqlite3_create_function(D,X,N,E,...)]
**          specify multiple implementations of the same function X with
**          the same number of arguments N but with different
**          encodings E, then the implementation where E matches the
**          database encoding shall preferred.
**
** {H16139} For an aggregate SQL function created using
**          [sqlite3_create_function(D,X,N,E,P,0,S,L)] the finalizer
**          function L shall always be invoked exactly once if the
**          step function S is called one or more times.
**
** {H16142} When SQLite invokes either the xFunc or xStep function of
**          an application-defined SQL function or aggregate created
**          by [sqlite3_create_function()] or [sqlite3_create_function16()],
**          then the array of [sqlite3_value] objects passed as the
**          third parameter shall be [protected sqlite3_value] objects.
