libthread
libthread(3LIB) Interface Libraries libthread(3LIB)NAME
libthread - threads library
SYNOPSIS
cc -mt [ flag... ] file... [ library... ]
DESCRIPTION
Historically, functions in libthread provided threading support. 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 imple-
mented as a filter on libc.so.1. New application development need not specify -lthread.
INTERFACES
The shared object libthread.so.1 provides the public interfaces defined below. See intro(3) for additional information on shared object
interfaces.
cond_broadcast cond_destroy
cond_init cond_reltimedwait
cond_signal cond_timedwait
cond_wait mutex_destroy
mutex_init mutex_lock
mutex_trylock mutex_unlock
rw_rdlock rw_tryrdlock
rw_trywrlock rw_unlock
rw_wrlock rwlock_destroy
rwlock_init sema_destroy
