NAME

cp_mempool_free - return memory block to a memory pool

SYNOPSIS

#include <cprops/mempool.h>

int cp_mempool_free(cp_mempool * const pool, void *data);

DESCRIPTION

cp_mempool_free returns a memory chunk obtained from cp_mempool_alloc or cp_mempool_calloc to the memory pool for reuse. Note that this does not actually release the memory block to the operating system. Memory allocated by cp_mempool is only returned to the operating system on pool destruction.

RETURN VALUE

zero on success or non-zero on locking failure if COLLECTION_MODE_NOSYNC is not set.
