- Performs an atomic compare exchange operation on a 16-bit unsigned integer.
-
- Performs an atomic compare exchange operation on the 16-bit unsigned integer
- specified by Value. If Value is equal to CompareValue, then Value is set to
- ExchangeValue and CompareValue is returned. If Value is not equal to CompareValue,
- then Value is returned. The compare exchange operation must be performed using
- MP safe mechanisms.
-
- @param Value A pointer to the 16-bit value for the compare exchange
- operation.
- @param CompareValue 16-bit value used in compare operation.
- @param ExchangeValue 16-bit value used in exchange operation.
-
- @return The original *Value before exchange.
