C++ (Cpp) runtime_futexwakeup Examples

Example #1

File: lock_futex.c Project: ChaosJohn/gcc

void
runtime_notewakeup(Note *n)
{
	if(runtime_xchg((uint32*)&n->key, 1))
		runtime_throw("notewakeup - double wakeup");
	runtime_futexwakeup((uint32*)&n->key, 1);
}

Example #2

File: lock_futex.c Project: vkargov/gcc

void
runtime_unlock(Lock *l)
{
	uint32 v;

	if(--runtime_m()->locks < 0)
		runtime_throw("runtime_unlock: lock count");

	v = runtime_xchg(&l->key, MUTEX_UNLOCKED);
	if(v == MUTEX_UNLOCKED)
		runtime_throw("unlock of unlocked lock");
	if(v == MUTEX_SLEEPING)
		runtime_futexwakeup(&l->key, 1);
}

Example #3

runtime_notewakeup(Note *n)
{
	runtime_xchg(&n->key, 1);
	runtime_futexwakeup(&n->key, 1);
}
