DESCRIPTION
     These integer constants designate various run-time status parameters that
     can be returned by sqlite3_status().

     SQLITE_STATUS_MEMORY_USED
             This parameter is the current amount of memory checked out using
             sqlite3_malloc(), either directly or indirectly.  The figure
             includes calls made to sqlite3_malloc() by the application and
             internal memory usage by the SQLite library.  Auxiliary page-
             cache memory controlled by SQLITE_CONFIG_PAGECACHE is not
             included in this parameter.  The amount returned is the sum of
             the allocation sizes as reported by the xSize method in
             sqlite3_mem_methods.

     SQLITE_STATUS_MALLOC_SIZE
             This parameter records the largest memory allocation request
             handed to sqlite3_malloc() or sqlite3_realloc() (or their
             internal equivalents).  Only the value returned in the
             *pHighwater parameter to sqlite3_status() is of interest.  The
             value written into the *pCurrent parameter is undefined.

     SQLITE_STATUS_MALLOC_COUNT
             This parameter records the number of separate memory allocations
             currently checked out.

     SQLITE_STATUS_PAGECACHE_USED
             This parameter returns the number of pages used out of the
             pagecache memory allocator that was configured using
             SQLITE_CONFIG_PAGECACHE.  The value returned is in pages, not in
             bytes.

     SQLITE_STATUS_PAGECACHE_OVERFLOW
             This parameter returns the number of bytes of page cache
             allocation which could not be satisfied by the
             SQLITE_CONFIG_PAGECACHE buffer and where forced to overflow to
             sqlite3_malloc().  The returned value includes allocations that
             overflowed because they where too large (they were larger than
             the "sz" parameter to SQLITE_CONFIG_PAGECACHE) and allocations
             that overflowed because no space was left in the page cache.

     SQLITE_STATUS_PAGECACHE_SIZE
             This parameter records the largest memory allocation request
             handed to pagecache memory allocator.  Only the value returned in
             the *pHighwater parameter to sqlite3_status() is of interest.
             The value written into the *pCurrent parameter is undefined.

     SQLITE_STATUS_SCRATCH_USED
             No longer used.

     SQLITE_STATUS_SCRATCH_OVERFLOW
             No longer used.

     SQLITE_STATUS_SCRATCH_SIZE
             No longer used.

     SQLITE_STATUS_PARSER_STACK
             The *pHighwater parameter records the deepest parser stack.  The
             *pCurrent value is undefined.  The *pHighwater value is only
             meaningful if SQLite is compiled with YYTRACKMAXSTACKDEPTH.

     New status parameters may be added from time to time.
