SQLITE_STATUS_MEMORY_USED(3) FreeBSD Library Functions Manual NAME SQLITE_STATUS_MEMORY_USED, SQLITE_STATUS_PAGECACHE_USED, SQLITE_STATUS_PAGECACHE_OVERFLOW, SQLITE_STATUS_SCRATCH_USED, SQLITE_STATUS_SCRATCH_OVERFLOW, SQLITE_STATUS_MALLOC_SIZE, SQLITE_STATUS_PARSER_STACK, SQLITE_STATUS_PAGECACHE_SIZE, SQLITE_STATUS_SCRATCH_SIZE, SQLITE_STATUS_MALLOC_COUNT - Status Parameters SYNOPSIS #define SQLITE_STATUS_MEMORY_USED #define SQLITE_STATUS_PAGECACHE_USED #define SQLITE_STATUS_PAGECACHE_OVERFLOW #define SQLITE_STATUS_SCRATCH_USED #define SQLITE_STATUS_SCRATCH_OVERFLOW #define SQLITE_STATUS_MALLOC_SIZE #define SQLITE_STATUS_PARSER_STACK #define SQLITE_STATUS_PAGECACHE_SIZE #define SQLITE_STATUS_SCRATCH_SIZE #define SQLITE_STATUS_MALLOC_COUNT 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.
