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.

aio_cancel	aio_error
aio_fsync	aio_read
aio_return
aio_waitn
clock_getres
clock_nanosleep
close
fork
mq_close
mq_notify
mq_receive
mq_reltimedsend_np
mq_setattr
mq_timedsend
nanosleep
sched_get_priority_min
sched_getscheduler
sched_setparam
sched_yield
sem_destroy
sem_init
sem_post
sem_timedwait
sem_unlink
shm_open
sigqueue
sigwaitinfo
timer_delete
timer_gettime

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

aio_cancel64	aio_error64
aio_fsync64	aio_read64
aio_return64
aio_waitn64
lio_listio64
