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

NAME

libumem - object-caching memory allocation library

SYNOPSIS

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

DESCRIPTION

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).
