PTHREAD_COND_WAIT(3)                    BSD Library Functions 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 *restrict cond, pthread_mutex_t *restrict mutex);

DESCRIPTION
     The pthread_cond_wait() function atomically unlocks the mutex argument and waits on the cond argument.
     Before returning control to the calling function, pthread_cond_wait() re-acquires the mutex.

RETURN VALUES
     If successful, the pthread_cond_wait() function will return zero.  Otherwise, 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_timedwait(3)

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