1-2) Atomically adds arg to the value pointed to by obj and returns the value obj held previously, as if by Template:cpp

3-4) Atomically adds arg to the value pointed to by obj and returns the value obj held previously, as if by Template:cpp

5-6) Atomically increments the pointer value, pointed to by obj, by arg, and returns the value obj held previously, as if by Template:cpp

7-8) Atomically increments the pointer value, pointed to by obj, by arg, and returns the value obj held previously, as if by Template:cpp

Parameters

obj	-	pointer to the atomic object to modify
arg	-	the value to add to the value stored in the atomic object
order	-	the memory sycnhronization ordering for this operation: all values are permitted.

Return value

The value held previously by the atomic object pointed to by obj

Exceptions
