The InterlockedOr routine atomically computes a bitwise OR operation.
Syntax
LONG InterlockedOr(
_Inout_ LONG volatile *Destination,
_In_ LONG Value
);
Parameters
- Destination [in, out]
-
A pointer to the variable to be ORed with Value. The result of the operation is stored in the variable.
- Value [in]
-
Specifies the value to be ORed with the variable that is pointed to by Destination.
