#include <pthread.h>
int pthread_cond_broadcast(pthread_cond_t *cond);
The pthread_cond_broadcast()
function unblocks all threads blocked on the specified condition
variable. The function has no effect if no threads are blocked on
the condition variable. pthread_cond_broadcast() may be
called by a thread whether or not it owns the mutex which threads
calling pthread_cond_wait() or pthread_cond_timedwait()
have associated with the condition variable during their waits.
However, if predictable scheduling behavior is required, then
that mutex should be locked by the thread calling
pthread_cond_broadcast().
- cond
-
Is the condition variable to broadcast.
On success, pthread_cond_broadcast()
returns 0. On error, one of the following values is returned:

cond does not refer to an
initialized condition variable.
