**
** These interfaces provide the same information as the [SQLITE_VERSION],
** [SQLITE_VERSION_NUMBER], and [SQLITE_SOURCE_ID] C preprocessor macros

** In such cases, the
** mutex must be exited an equal number of times before another thread
** can enter.)^  If the same thread tries to enter any mutex other
** than an SQLITE_MUTEX_RECURSIVE more than once, the behavior is undefined.
**
** ^(Some systems (for example, Windows 95) do not support the operation
** implemented by sqlite3_mutex_try().  On those systems, sqlite3_mutex_try()
** will always return SQLITE_BUSY. In most cases the SQLite core only uses
** sqlite3_mutex_try() as an optimization, so this is acceptable
** behavior. The exceptions are unix builds that set the
** SQLITE_ENABLE_SETLK_TIMEOUT build option. In that case a working
** sqlite3_mutex_try() is required.)^
**
** ^The sqlite3_mutex_leave() routine exits a mutex that was
** previously entered by the same thread.   The behavior
** is undefined if the mutex is not currently entered by the
** calling thread or is not currently allocated.
**
** ^If the argument to sqlite3_mutex_enter(), sqlite3_mutex_try(),

**   an OOM condition or IO error), an appropriate SQLite error code is
**   returned.
**
**   This function may be quite inefficient if used with an FTS5 table
**   created with the "columnsize=0" option.
**
** xColumnText:
**   If parameter iCol is less than zero, or greater than or equal to the
**   number of columns in the table, SQLITE_RANGE is returned.
**
**   Otherwise, this function attempts to retrieve the text of column iCol of
**   the current document. If successful, (*pz) is set to point to a buffer
**   containing the text in utf-8 encoding, (*pn) is set to the size in bytes
**   (not characters) of the buffer and SQLITE_OK is returned. Otherwise,
**   if an error occurs, an SQLite error code is returned and the final values
**   of (*pz) and (*pn) are undefined.
**
** xPhraseCount:
**   Returns the number of phrases in the current query expression.
**
** xPhraseSize:
**   If parameter iCol is less than zero, or greater than or equal to the
**   number of phrases in the current query, as returned by xPhraseCount,
**   0 is returned. Otherwise, this function returns the number of tokens in
**   phrase iPhrase of the query. Phrases are numbered starting from zero.
**
** xInstCount:
**   Set *pnInst to the total number of occurrences of all phrases within
**   the query within the current row. Return SQLITE_OK if successful, or
**   an error code (i.e. SQLITE_NOMEM) if an error occurs.
**
**   This API can be quite slow if used with an FTS5 table created with the
**   "detail=none" or "detail=column" option. If the FTS5 table is created
**   with either "detail=none" or "detail=column" and "content=" option
**   (i.e. if it is a contentless table), then this API always returns 0.
**
** xInst:
**   Query for the details of phrase match iIdx within the current row.
**   Phrase matches are numbered starting from zero, so the iIdx argument
**   should be greater than or equal to zero and smaller than the value
**   output by xInstCount(). If iIdx is less than zero or greater than
**   or equal to the value returned by xInstCount(), SQLITE_RANGE is returned.
**
**   Otherwise, output parameter *piPhrase is set to the phrase number, *piCol
**   to the column in which it occurs and *piOff the token offset of the
**   first token of the phrase. SQLITE_OK is returned if successful, or an
**   error code (i.e. SQLITE_NOMEM) if an error occurs.
**
**   This API can be quite slow if used with an FTS5 table created with the
**   "detail=none" or "detail=column" option.
**
** xRowid:
**   Returns the rowid of the current row.
**

**   current query is executed. Any column filter that applies to
**   phrase iPhrase of the current query is included in $p. For each
**   row visited, the callback function passed as the fourth argument
**   is invoked. The context and API objects passed to the callback
**   function may be used to access the properties of each matched row.
**   Invoking Api.xUserData() returns a copy of the pointer passed as
**   the third argument to pUserData.
**
**   If parameter iPhrase is less than zero, or greater than or equal to
**   the number of phrases in the query, as returned by xPhraseCount(),
**   this function returns SQLITE_RANGE.
**
**   If the callback function returns any value other than SQLITE_OK, the
**   query is abandoned and the xQueryPhrase function returns immediately.
**   If the returned value is SQLITE_DONE, xQueryPhrase returns SQLITE_OK.
**   Otherwise, the error code is propagated upwards.
**
**   If the query runs to completion without incident, SQLITE_OK is returned.

**   See xPhraseFirstColumn above.
**
** xQueryToken(pFts5, iPhrase, iToken, ppToken, pnToken)
**   This is used to access token iToken of phrase iPhrase of the current
**   query. Before returning, output parameter *ppToken is set to point
**   to a buffer containing the requested token, and *pnToken to the
**   size of this buffer in bytes.
**
**   If iPhrase or iToken are less than zero, or if iPhrase is greater than
**   or equal to the number of phrases in the query as reported by
**   xPhraseCount(), or if iToken is equal to or greater than the number of
**   tokens in the phrase, SQLITE_RANGE is returned and *ppToken and *pnToken
     are both zeroed.
**
**   The output text is not a copy of the query text that specified the
**   token. It is the output of the tokenizer module. For tokendata=1
**   tables, this includes any embedded 0x00 and trailing data.
**
** xInstToken(pFts5, iIdx, iToken, ppToken, pnToken)
**   This is used to access token iToken of phrase hit iIdx within the
**   current row. If iIdx is less than zero or greater than or equal to the
**   value returned by xInstCount(), SQLITE_RANGE is returned.  Otherwise,
**   output variable (*ppToken) is set to point to a buffer containing the
**   matching document token, and (*pnToken) to the size of that buffer in
**   bytes. This API is not available if the specified token matches a
**   prefix query term. In that case both output variables are always set
**   to 0.
**
**   The output text is not a copy of the document text that was tokenized.
**   It is the output of the tokenizer module. For tokendata=1 tables, this
**   includes any embedded 0x00 and trailing data.
**
**   This API can be quite slow if used with an FTS5 table created with the
**   "detail=none" or "detail=column" option.
