PTHREAD_COND_WAIT(3) BSD Library Functions Manual PTHREAD_COND_WAIT(3) NAME pthread_cond_wait -- wait on a condition variable LIBRARY Reentrant C Library (libc_r, -lc_r) SYNOPSIS #include <pthread.h> int pthread_cond_wait(pthread_cond_t *cond, pthread_mutex_t *mutex); DESCRIPTION The pthread_cond_wait() function atomically blocks the current thread waiting on the condition variable specified by cond, and unblocks the mu- tex specified by mutex. The waiting thread unblocks only after another thread calls pthread_cond_signal(3), or pthread_cond_broadcast(3) with the same condition variable, and the current thread reacquires the lock on mutex. RETURN VALUES If successful, the pthread_cond_wait() function will return zero. Other- wise an error number will be returned to indicate the error. ERRORS pthread_cond_wait() will fail if: [EINVAL] The value specified by cond or the value specified by mutex is invalid. SEE ALSO pthread_cond_broadcast(3), pthread_cond_destroy(3), pthread_cond_init(3), pthread_cond_signal(3), pthread_cond_timedwait(3) STANDARDS pthread_cond_wait() conforms to ISO/IEC 9945-1:1996 ("POSIX.1").
