These integer constants designate various run-time status parameters
that can be returned by sqlite3_status().
R-30814-53756:[- 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. 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.
]
R-18160-48734:[- 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.
]
R-29137-58191:[- SQLITE_STATUS_MALLOC_COUNT
- This parameter records the number of separate memory allocations
currently checked out.
]
R-36399-45840:[- 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.
]
R-46798-18657:[- 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.
]
R-22517-09812:[- 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.
]
R-15554-05778:[- SQLITE_STATUS_SCRATCH_USED
- 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.
]
R-19021-59629:[- SQLITE_STATUS_SCRATCH_OVERFLOW
- 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.
]
R-28888-42274:[- SQLITE_STATUS_SCRATCH_SIZE
- 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.
]
R-37652-04911:[- 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.
