** CAPI3REF: Tracing And Profiling Functions {H12280} <S60400>
** EXPERIMENTAL
**
** These routines register callback functions that can be used for
** tracing and profiling the execution of SQL statements.
**
** The callback function registered by sqlite3_trace() is invoked at
** various times when an SQL statement is being run by [sqlite3_step()].
** The callback returns a UTF-8 rendering of the SQL statement text
** as the statement first begins executing. Additional callbacks occur
** as each triggered subprogram is entered. The callbacks for triggers
** contain a UTF-8 SQL comment that identifies the trigger.
**
** The callback function registered by sqlite3_profile() is invoked
** as each SQL statement finishes. The profile callback contains
** the original statement text and an estimate of wall-clock time
** of how long that statement took to run.
**
** INVARIANTS:
**
** {H12281} The callback function registered by [sqlite3_trace()] is
** whenever an SQL statement first begins to execute and
** whenever a trigger subprogram first begins to run.
**
** {H12282} Each call to [sqlite3_trace()] overrides the previously
** registered trace callback.
**
** {H12283} A NULL trace callback disables tracing.
**
** {H12284} The first argument to the trace callback is a copy of
** the pointer which was the 3rd argument to [sqlite3_trace()].
**
** {H12285} The second argument to the trace callback is a
** zero-terminated UTF-8 string containing the original text
** of the SQL statement as it was passed into [sqlite3_prepare_v2()]
** or the equivalent, or an SQL comment indicating the beginning
** of a trigger subprogram.
**
** {H12287} The callback function registered by [sqlite3_profile()] is invoked
** as each SQL statement finishes.
**
** {H12288} The first parameter to the profile callback is a copy of
** the 3rd parameter to [sqlite3_profile()].
**
** {H12289} The second parameter to the profile callback is a

** CAPI3REF: Create Or Redefine SQL Functions {H16100} <S20200>
** KEYWORDS: {function creation routines}
** KEYWORDS: {application-defined SQL function}
** KEYWORDS: {application-defined SQL functions}
**
** These two functions (collectively known as "function creation routines")
** are used to add SQL functions or aggregates or to redefine the behavior
** of existing SQL functions or aggregates. The only difference between the
** two is that the second parameter, the name of the (scalar) function or
** aggregate, is encoded in UTF-8 for sqlite3_create_function() and UTF-16
** for sqlite3_create_function16().
**
** The first parameter is the [database connection] to which the SQL
** function is to be added. If a single program uses more than one database
** connection internally, then SQL functions must be added individually to
** each database connection.
**
** 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
** more efficient with one encoding than another. It is allowed to
** invoke sqlite3_create_function() or sqlite3_create_function16() multiple
** times with the same function but with different values of eTextRep.
** When multiple implementations of the same function are available, SQLite
** will pick the one that involves the least amount of data conversion.
** If there is only a single implementation which does not care what text
** encoding is used, then the fourth argument should be [SQLITE_ANY].
**
** The fifth parameter is an arbitrary pointer. The implementation of the
** function can gain access to this pointer using [sqlite3_user_data()].
**
** The seventh, eighth and ninth parameters, xFunc, xStep and xFinal, are
** pointers to C-language functions that implement the SQL function or
** aggregate. A scalar SQL function requires an implementation of the xFunc
** callback only, NULL pointers should be passed as the xStep and xFinal
** parameters. An aggregate SQL function requires an implementation of xStep
** 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
** and having a preferred text encoding of E.
**
** {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.
**
** {H16118} Either F must be NULL and S and L are non-NULL or else F
** is non-NULL and S and L are NULL, otherwise
** [sqlite3_create_function(D,X,N,E,P,F,S,L)] returns [SQLITE_ERROR].
**
** {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

** CAPI3REF: Obtaining SQL Function Parameter Values {H15100} <S20200>
**
** The C-language implementation of SQL functions and aggregates uses
** this set of interface routines to access the parameter values on
** the function or aggregate.
**
** The xFunc (for scalar functions) or xStep (for aggregates) parameters
** to [sqlite3_create_function()] and [sqlite3_create_function16()]
** define callbacks that implement the SQL functions and aggregates.
** The 4th parameter to these callbacks is an array of pointers to
** [protected sqlite3_value] objects. There is one [sqlite3_value] object for
** each parameter to the SQL function. These routines are used to
** extract values from the [sqlite3_value] objects.
**
** These routines work only with [protected sqlite3_value] objects.
** Any attempt to use these routines on an [unprotected sqlite3_value]
** object results in undefined behavior.
**
** These routines work just like the corresponding [column access functions]
** except that these routines take a single [protected sqlite3_value] object
** pointer instead of a [sqlite3_stmt*] pointer and an integer column number.
**
** The sqlite3_value_text16() interface extracts a UTF-16 string
** in the native byte-order of the host machine. The
** sqlite3_value_text16be() and sqlite3_value_text16le() interfaces
** extract UTF-16 strings as big-endian and little-endian respectively.
**
** The sqlite3_value_numeric_type() interface attempts to apply
** numeric affinity to the value. This means that an attempt is
** made to convert the value to an integer or floating point. If
** such a conversion is possible without loss of information (in other
** words, if the value is a string that looks like a number)
** then the conversion is performed. Otherwise no conversion occurs.
** The [SQLITE_INTEGER | datatype] after conversion is returned.
**
** Please pay particular attention to the fact that the pointer returned
** from [sqlite3_value_blob()], [sqlite3_value_text()], or
** [sqlite3_value_text16()] can be invalidated by a subsequent call to
** [sqlite3_value_bytes()], [sqlite3_value_bytes16()], [sqlite3_value_text()],
** or [sqlite3_value_text16()].
**
** These routines must be called from the same thread as
** the SQL function that supplied the [sqlite3_value*] parameters.
**
** INVARIANTS:
**
** {H15103} The [sqlite3_value_blob(V)] interface converts the
** [protected sqlite3_value] object V into a BLOB and then
** returns a pointer to the converted value.
**
** {H15106} The [sqlite3_value_bytes(V)] interface returns the
** number of bytes in the BLOB or string (exclusive of the
** zero terminator on the string) that was returned by the
** most recent call to [sqlite3_value_blob(V)] or
** [sqlite3_value_text(V)].
**
** {H15109} The [sqlite3_value_bytes16(V)] interface returns the
** number of bytes in the string (exclusive of the
** zero terminator on the string) that was returned by the
** most recent call to [sqlite3_value_text16(V)],
** [sqlite3_value_text16be(V)], or [sqlite3_value_text16le(V)].
**
** {H15112} The [sqlite3_value_double(V)] interface converts the
** [protected sqlite3_value] object V into a floating point value and
** returns a copy of that value.
**
** {H15115} The [sqlite3_value_int(V)] interface converts the
** [protected sqlite3_value] object V into a 64-bit signed integer and
** returns the lower 32 bits of that integer.
**
** the destructor will be called before the metadata is dropped.
**
** In practice, metadata is preserved between function calls for
** expressions that are constant at compile time. This includes literal
** values and SQL variables.
**
** These routines must be called from the same thread in which
** the SQL function is running.
**
** INVARIANTS:

**
** These routines are used by the xFunc or xFinal callbacks that
** implement SQL functions and aggregates. See
** [sqlite3_create_function()] and [sqlite3_create_function16()]
** for additional information.
**
** These functions work very much like the [parameter binding] family of
** functions used to bind values to host parameters in prepared statements.
** Refer to the [SQL parameter] documentation for additional information.
**
** The sqlite3_result_blob() interface sets the result from
** an application-defined function to be the BLOB whose content is pointed
** to by the second parameter and which is N bytes long where N is the
** third parameter.
**
** The sqlite3_result_zeroblob() interfaces set the result of
** the application-defined function to be a BLOB containing all zero
** bytes and N bytes in size, where N is the value of the 2nd parameter.
**
** The sqlite3_result_double() interface sets the result from
** an application-defined function to be a floating point value specified
** by its 2nd argument.
**
** The sqlite3_result_error() and sqlite3_result_error16() functions
** cause the implemented SQL function to throw an exception.
** SQLite uses the string pointed to by the
** 2nd parameter of sqlite3_result_error() or sqlite3_result_error16()
** as the text of an error message. SQLite interprets the error
** message string from sqlite3_result_error() as UTF-8. SQLite
** interprets the string from sqlite3_result_error16() as UTF-16 in native
** byte order. If the third parameter to sqlite3_result_error()
** or sqlite3_result_error16() is negative then SQLite takes as the error
** message all text up through the first zero character.
** If the third parameter to sqlite3_result_error() or
** sqlite3_result_error16() is non-negative then SQLite takes that many
** bytes (not characters) from the 2nd parameter as the error message.
** The sqlite3_result_error() and sqlite3_result_error16()
** routines make a private copy of the error message text before
** they return. Hence, the calling function can deallocate or
** modify the text after they return without harm.
** The sqlite3_result_error_code() function changes the error code
** returned by SQLite as a result of an error in a function. By default,
** the error code is SQLITE_ERROR. A subsequent call to sqlite3_result_error()
** or sqlite3_result_error16() resets the error code to SQLITE_ERROR.
**
** The sqlite3_result_toobig() interface causes SQLite to throw an error
** indicating that a string or BLOB is to long to represent.
**
** The sqlite3_result_nomem() interface causes SQLite to throw an error
** indicating that a memory allocation failed.
**
** The sqlite3_result_int() interface sets the return value
** of the application-defined function to be the 32-bit signed integer
** value given in the 2nd argument.
** The sqlite3_result_int64() interface sets the return value
