NAME

sqlite3_release_memory — attempt to free heap memory

SYNOPSIS

#include <sqlite3.h>

int
sqlite3_release_memory(int);

DESCRIPTION

The sqlite3_release_memory() interface attempts to free N bytes of heap memory by deallocating non-essential memory allocations held by the database library. Memory used to cache database pages to improve performance is an example of non-essential memory. sqlite3_release_memory() returns the number of bytes actually freed, which might be more or less than the amount requested. The sqlite3_release_memory() routine is a no-op returning zero if SQLite is not compiled with SQLITE_ENABLE_MEMORY_MANAGEMENT.
