Detailed Description
Define a basic atomic counter.
Provide basic counter operations for an atomic counter represented internally by TNCBIAtomicValue.
- Note
- CAtomicCounter has no constructor and is initialized only when created as static object. In all other cases Set(0) must be called to initialize the counter. CAtomicCounter_WithAutoInit can be used instead of CAtomicCounter if the initialization is required.
- TNCBIAtomicValue does not imply any assumptions about the size and the signedness of the value. It is at least as big as int datatype and can be signed on some platforms and unsigned on others.
