PTHREAD_COND_WAIT(3) BSD Programmer's Manual PTHREAD_COND_WAIT(3)
NAME
pthread_cond_wait - wait on a condition variable
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

STANDARDS
pthread_cond_wait() conforms to ISO/IEC 9945-1:1996 ("POSIX").
