NAME
sqlite3_release_memory —
Attempt To
Free Heap Memory
SYNOPSIS
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.
