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

SYNOPSIS
     #include <pthread.h>

     int pthread_cond_broadcast (cond)
     pthread_cond_t *cond;

DESCRIPTION
     The pthread_cond_broadcast function wakes up all of the threads that are
     waiting for the specified condition to be satisfied.

     The cond argument specifies the condition variable being waited on.

     The call has no effect if no threads are waiting on the condition.

NOTES
     This interface is based on draft 4 of the IEEE P1003.4a standard, and
     will be changed to conform to the final version.

DIAGNOSTICS
     Upon successful completion, a value of 0 (zero) is returned. Otherwise,
     -1 is returned and errno is set to indicate the error.

ERRORS
     If the pthread_cond_broadcast function fails, errno may be set to the
     following value:

     [EINVAL]  The value specified by the cond argument is invalid.
