| SQLiteStatusCode Enumeration |
These constants designate various run-time status parameters that can be
returned by Status(SQLiteStatusCode, Int32, Int32, Boolean).

SyntaxMembers| Member name | Value | Description | |
|---|---|---|---|
| MemoryUsed | 0 | 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. Scratch memory controlled by SQLITE_CONFIG_SCRATCH and 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. | |
| PageCacheUsed | 1 | 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. | |
| PageCacheOverflow | 2 | 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. | |
| ScratchUsed | 3 | This parameter returns the number of allocations used out of the scratch memory allocator configured using SQLITE_CONFIG_SCRATCH. The value returned is in allocations, not in bytes. Since a single thread may only have one scratch allocation outstanding at time, this parameter also reports the number of threads using scratch memory at the same time. | |
| ScratchOverflow | 4 | This parameter returns the number of bytes of scratch memory allocation which could not be satisfied by the SQLITE_CONFIG_SCRATCH buffer and where forced to overflow to sqlite3_malloc(). The values returned include overflows because the requested allocation was too larger (that is, because the requested allocation was larger than the "sz" parameter to SQLITE_CONFIG_SCRATCH) and because no scratch buffer slots were available. | |
| MallocSize | 5 | 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. | |
| ParserStack | 6 | This parameter records the deepest parser stack. It is only meaningful if SQLite is compiled with YYTRACKMAXSTACKDEPTH. | |
| PageCacheSize | 7 | 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. | |
| ScratchSize | 8 | This parameter records the largest memory allocation request handed to scratch 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. | |
| MallocCount | 9 | This parameter records the number of separate memory allocations currently checked out. |
