Anyone know if there's a macro, CXX extension, gcc extension, POSIX call, or
any other Mac OS X call that does an interlocked increment/decrement (adds 1
or subtracts 1 to an integer). Yes, I know I can use a mutex, but life is
way easier (as well as overhead is a lot lower) when this kind of call is
available (especially since these days the CPU has dedicated instruction for
it). For example, Win32 has them:
long InterlockedIncrement( long* );
long InterlockedDecrement( long* );
Thanks,
Andy
