atomicIntAnd
fn
uint atomicIntAnd(ref uint atomic, uint val)Performs an atomic bitwise 'and' of the value of atomic and val, storing the result back in atomic.
This call acts as a full compiler and hardware memory barrier.
Think of this operation as an atomic version of { tmp = *atomic; *atomic &= val; return tmp; }.
While atomic has a volatile qualifier, this is a historical artifact and the pointer passed to it should not be volatile.
Parameters
atomic | a pointer to a #gint or #guint |
val | the value to 'and' |
Returns
the value of atomic before the operation, unsigned
