SQLITE3_MEMORY_USED(3)

NAME
sqlite3_memory_used, sqlite3_memory_highwater - memory allocator statistics

SYNOPSIS
#include <sqlite3.h>
sqlite3_int64
sqlite3_memory_used(void);
sqlite3_int64
sqlite3_memory_highwater(int resetFlag);

DESCRIPTION
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.
