pointerBitTrylock

fnbool pointerBitTrylock(void * address, int lockBit)

This is equivalent to [glib.global.bitTrylock], but working on pointers (or other pointer-sized values).

For portability reasons, you may only lock on the bottom 32 bits of the pointer.

While address has a volatile qualifier, this is a historical artifact and the argument passed to it should not be volatile.

Parameters

addressa pointer to a #gpointer-sized value
lockBita bit value between 0 and 31

Returns

true if the lock was acquired
