al_broadcast_cond

void al_broadcast_cond(ALLEGRO_COND *cond)
 Introduced in 5.0.0

Unblock all threads currently waiting on a condition variable. That is, broadcast that some condition which those threads were waiting for has become true.

See also: al_signal_cond.

Note: The pthreads spec says to lock the mutex associated with cond before signalling for predictable scheduling behaviour.

Examples: ex_threads2
