librt(3LIB)                   Interface Libraries                  librt(3LIB)



NAME
       librt, libposix4 - POSIX.1b Realtime Extensions library

SYNOPSIS
       cc [ flag... ] file... -lrt [ library... ]

DESCRIPTION
       Historically, functions in this library provided many of the interfaces
       specified by the POSIX.1b Realtime Extension.  See  standards(7).  This
       functionality now resides in libc(3LIB).


       This  library  is maintained to provide backward compatibility for both
       runtime and compilation environments. The shared object is  implemented
       as  a filter on libc.so.1. New application development need not specify
       -lrt.

INTERFACES
       The shared objects librt.so.1 and  libposix4.so.1  provide  the  public
       interfaces  defined  below.  See intro(3) for additional information on
       shared object interfaces.

       The following interfaces are unique  to  the  32-bit  version  of  this
       library:
