C++ (Cpp) ResourceOwnerForgetSnapshot Examples

Example #1

/*
 * UnregisterSnapshotFromOwner
 *		As above, but use the specified resource owner
 */
void

		return;

	Assert(snapshot->regd_count > 0);

	RegisteredSnapshots--;
	if (--snapshot->regd_count == 0 && snapshot->active_count == 0)
	{
		FreeSnapshot(snapshot);
		SnapshotResetXmin();
	}
}
