The atomic functions preserve volatile semantics - they only perform the accesses specified. Add the volatile qualifier to the value pointer to reflect this. This does not change existing caller code - it's equivalent to adding a const qualifier to indicate we don't write to a pointer - it means people can pass us qualified pointers without casts, letting the compile check const- or volatile-correctness. This is consistent with C11 <stdatomic.h>, which volatile-qualifies its equivalent functions. Note that this useage of volatile has nothing to do with the atomicity - objects accessed via the atomic functions do not need to be volatile. But it does permit these calls to be used on objects which have been declared volatile. |
