void atomic_flag_clear( volatile atomic_flag* obj );
(1) (since C11)
void atomic_flag_clear_explicit( volatile atomic_flag* obj, memory_order order );
(2) (since C11)

Atomically changes the state of a atomic_flag pointed to by obj to clear (false). The first version orders memory accesses according to memory_order_seq_cst, the second version orders memory accesses according to order.

[edit] Parameters

obj - pointer to the atomic flag object to modify
order - the memory synchronization ordering for this operation: all values are permitted

[edit] Return value
