## SQLite C Interface

## Attempt To Free Heap Memory

>     int sqlite3_release_memory(int);

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.

### Invariants:

H17341 | The sqlite3_release_memory(N) interface attempts to free N bytes of heap memory by deallocating non-essential memory allocations held by the database library.
H16342 | The sqlite3_release_memory(N) returns the number of bytes actually freed, which might be more or less than the amount requested.
