** CAPI3REF: SQL Trace Event Codes
** KEYWORDS: SQLITE_TRACE
**
** These constants identify classes of events that can be monitored
** using the [sqlite3_trace_v2()] tracing logic.  The third argument
** to [sqlite3_trace_v2()] is an OR-ed combination of one or more of
** the following constants.  The first argument to the trace callback
** is one of the following constants.
**
** New tracing constants may be added in future releases.
**
** A trace callback has four arguments: xCallback(T,C,P,X).
** The T argument is one of the integer type codes above.
** The C argument is a copy of the context pointer passed in as the
** fourth argument to [sqlite3_trace_v2()].
** The P argument is a pointer whose meaning depends on T.
** The X argument is an unsigned 64-bit integer whose meaning also
** depends on T.
**
** <dl>
** [[SQLITE_TRACE_SQL]] <dt>SQLITE_TRACE_SQL</dt>
** <dd>An SQLITE_TRACE_SQL callback provides the same functionality
** as the legacy [sqlite3_trace()] callback.
** The P argument is a pointer to the constant UTF-8 string that is text
** describing an SQL statement that is starting to run with all
** [bound parameter] expanded.  The X argument is unused.  The size
** of the expansion of [bound parameters] is limited by the
** [SQLITE_TRACE_SIZE_LIMIT] compile-time option.
**
** [[SQLITE_TRACE_STMT]] <dt>SQLITE_TRACE_STMT</dt>
** <dd>An SQLITE_TRACE_STMT callback is invoked on the same occasions
** as SQLITE_TRACE_SQL.  The difference is that the P argument is a
** pointer to the [prepared statement] rather than an SQL string.
** The X argument is unused.
**
** [[SQLITE_TRACE_PROFILE]] <dt>SQLITE_TRACE_PROFILE</dt>
** <dd>An SQLITE_TRACE_PROFILE callback provides approximately the same
** information as is provided by the [sqlite3_profile()] callback.
** The P argument is a pointer to the [prepared statement] and the
** X argument is an estimate of the number of nanosecond for which
** the prepared statement ran.  The SQLITE_TRACE_PROFILE callback is
** invoked when the statement finishes.
**
** [[SQLITE_TRACE_ROW]] <dt>SQLITE_TRACE_ROW</dt>
** <dd>An SQLITE_TRACE_ROW callback is invoked whenever a prepared
** statement generates a single row of result.  
** The P argument is a pointer to the [prepared statement] and the
** X argument is unused.
**
** [[SQLITE_TRACE_CLOSE]] <dt>SQLITE_TRACE_CLOSE</dt>
** <dd>An SQLITE_TRACE_CLOSE callback is invoked when a database
** connection closes.
** The P argument is a pointer to the [database connection] object
** and the X argument is unused.

/*
** CAPI3REF: SQL Trace Hook
** METHOD: sqlite3
**
** The sqlite3_trace_v2(D,X,M,P) interface registers a trace callback
** function X against [database connection] D, using property mask M
** and context pointer P.  If the X callback is
** NULL or if the M mask is zero, then tracing is disabled.  The
** M argument must be one or more of the [SQLITE_TRACE]
** constants.
**
** Each call to either sqlite3_trace() or sqlite3_trace_v2() overrides 
** (cancels) any prior calls to sqlite3_trace() or sqlite3_trace_v2().
**
** The X callback is invoked whenever any of the events identified by 
** mask M occur.  The integer return value from the callback is currently
** ignored, though this may change in future releases.  Callback
** implementations should return zero to ensure future compatibility.
**
** A trace callback is invoked with four arguments: callback(T,C,P,X).
** The T argument is one of the [SQLITE_TRACE]
** constants to indicate why the callback was invoked.
** The C argument is a copy of the context pointer.
** The P and X arguments are a pointer and an unsigned 64-bit integer
** whose meanings depend on T.
**
** The sqlite3_trace_v2() interface is intended to replace the legacy
** interfaces [sqlite3_trace()] and [sqlite3_profile()], both of which
** are deprecated.
