memory allocator statistics
#include

sqlite3_memory_used(void);
sqlite3_int64
sqlite3_memory_highwater(int
resetFlag);
SQLite provides these two interfaces for reporting on the status
of the
sqlite3_malloc(),
sqlite3_free(),
and
sqlite3_realloc()
routines, which form the built-in memory allocation subsystem.
The
sqlite3_memory_used()
routine returns the number of bytes of memory currently outstanding
(malloced but not freed). The
sqlite3_memory_highwater()
routine returns the maximum value of
sqlite3_memory_used() since the high-water mark was
last reset. The values returned by
sqlite3_memory_used() and
sqlite3_memory_highwater() include any overhead
added by SQLite in its implementation of
sqlite3_malloc(), but not overhead added by the any
underlying system library routines that
sqlite3_malloc() may call.
The memory high-water mark is reset to
the current value of
sqlite3_memory_used()
if and only if the parameter to
sqlite3_memory_highwater()
is true. The value returned by sqlite3_memory_highwater(1) is the high-water
mark prior to the reset.
These declarations were extracted from the interface documentation at line 3075.
