pthread_cond_broadcast(3-thr)                 pthread_cond_broadcast(3-thr)

NAME
     pthreadcondbroadcast - wakes all threads that are waiting on a con-
     dition variable

SYNOPSIS
     #include <pthread.h>

     int pthreadcondbroadcast(pthreadcondt *cond);

PARAMETERS
     cond      Condition variable broadcast.

DESCRIPTION
     The pthreadcondbroadcast() routine wakes all threads waiting on a
     condition variable. Calling this routine implies that data guarded by
     the associated mutex has changed so that it might be possible for one
     or more waiting threads to proceed. If any one waiting thread might be
     able to proceed, call pthreadcondsignal().

     Call this routine when the associated mutex is either locked or
     unlocked.

RETURN VALUES
     If the function fails, errno may be set to one of the following
     values:

     EINVAL    The value specified by cond is invalid.
