Corresponding intrinsic to wasm’s memory.atomic.notify instruction
This function will notify a number of threads blocked on the address
indicated by ptr. Threads previously blocked with the i32_atomic_wait
and i64_atomic_wait functions above will be woken up.
The waiters argument indicates how many waiters should be woken up (a
maximum). If the value is zero no waiters are woken up.
Return value
Returns the number of waiters which were actually notified.
