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 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.
