PTHREAD_COND_WAIT(3)   FreeBSD Library Functions Manual	  PTHREAD_COND_WAIT(3)

NAME
     pthread_cond_wait -- wait on a condition variable

LIBRARY
     Reentrant C Library (libc_r, -lc_r)
     POSIX Threads Library (libpthread,	-lpthread)
     1:1 Threading Library (libthr, -lthr)

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
     mutex 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
     The pthread_cond_wait() function 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
     The pthread_cond_wait() function conforms to ISO/IEC 9945-1:1996
     (``POSIX.1'').
