LIBUMEM(3LIB) Interface Libraries LIBUMEM(3LIB)

libumem - object-caching memory allocation library

cc [ flag... ] file... -lumem [ library... ]
#include <umem.h>

Functions in this library provide fast, scalable object-caching memory allocation with multithreaded application support. In addition to the standard malloc(3C) family of functions and the more flexible umem_alloc(3MALLOC) family, libumem provides powerful object-caching services as described in umem_cache_create(3MALLOC).

The libumem library also provides extensive debugging support, including detection of memory leaks, buffer overruns, multiple frees, use of uninitialized data, use of freed data, and many other common programming errors. See umem_debug(3MALLOC).

The shared object libumem.so.1 provides the public interfaces defined below. See Intro(3) for additional information on shared object interfaces.
