Detailed Description

Components for performing atomic operations.


Macro Definition Documentation

#define ATOMIC_BOOL_LOCK_FREE

Lock-free property.

0 indicates that the types are never lock-free. 1 indicates that the types are sometimes lock-free. 2 indicates that the types are always lock-free.
