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(5).  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 applica-
     tion 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.
