  NAME

      pthread_cond_broadcast - Wakes all threads that are waiting on
                               a condition variable

  SYNOPSIS

      #include <pthread.h>

      int pthread_cond_broadcast(pthread_cond_t *cond);

  PARAMETERS

      cond                Condition variable broadcast.

  DESCRIPTION

  The pthread_cond_broadcast() routine wakes all threads waiting on a con-
  dition 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 pthread_cond_signal().

  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:

    Return   Error      Description
    ___________________________________________________________
    0                   Successful completion.

    -1      [EINVAL]    The value specified by cond is invalid.
