.SH NAME
libumem \- object-caching memory allocation library
.SH SYNOPSIS
.nf
cc [ \fIflag\fR... ] \fIfile\fR... \fB-lumem\fR [ \fIlibrary\fR... ]
#include <\fBumem.h\fR>
.fi
.SH DESCRIPTION
Functions in this library provide fast, scalable object-caching memory
allocation with multithreaded application support. In addition to the standard
\fBmalloc\fR(3C) family of functions and the more flexible
\fBumem_alloc\fR(3MALLOC) family, \fBlibumem\fR provides powerful
object-caching services as described in \fBumem_cache_create\fR(3MALLOC).
.sp
.LP
The \fBlibumem\fR 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 \fBumem_debug\fR(3MALLOC).
.SH INTERFACES
The shared object \fBlibumem.so.1\fR provides the public interfaces defined
below. See \fBIntro\fR(3) for additional information on shared object
interfaces.
