- Performs an atomic compare exchange operation on a 64-bit unsigned integer.
-
- Performs an atomic compare exchange operation on the 64-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.

- operation.
- @param CompareValue 64-bit value used in compare operation.
- @param ExchangeValue 64-bit value used in exchange operation.

- @return The original *Value before exchange.
