NAME
librt, libposix4 - POSIX.1b Realtime Extensions library
SYNOPSIS
cc [ flag... ] file... -lrt [ library... ]
DESCRIPTION
Functions in this library provide most of the interfaces specified by the POSIX.1b Realtime Extension. See standards(5). Specifically, this includes the interfaces defined under the Asynchronous I/O, Message Passing, Process Scheduling, Realtime Signals Extension, Sema- phores, Shared Memory Objects, Synchronized I/O, and Timers options. The interfaces defined under the Memory Mapped Files, Process Memory Locking, and Range Memory Locking options are provided in libc(3LIB). See the man pages for the individual interfaces in section 3RT for information on required headers. The name libposix4 is maintained for backward compatibility and should be avoided. librt is the preferred name for this library.
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_suspend aio_waitn aio_write clock_getres clock_gettime clock_nanosleep clock_settime close fdatasync fork lio_listio mq_close mq_getattr mq_notify mq_open mq_receive mq_reltimedreceive_np mq_reltimedsend_np mq_send mq_setattr mq_timedreceive mq_timedsend mq_unlink nanosleep sched_get_priority_max sched_get_priority_min sched_getparam sched_getscheduler sched_rr_get_interval sched_setparam sched_setscheduler sched_yield sem_close sem_destroy sem_getvalue sem_init sem_open sem_post sem_reltimedwait_np sem_timedwait sem_trywait sem_unlink sem_wait shm_open shm_unlink sigqueue sigtimedwait sigwaitinfo timer_create timer_delete timer_getoverrun timer_gettime timer_settime The following interfaces are unique to the 32-bit version of this library: aio_cancel64 aio_error64 aio_fsync64 aio_read64 aio_return64 aio_suspend64 aio_waitn64 aio_write64 lio_listio64
