These functions enable the incrementing (by one) of the value stored in target to occur in an atomic manner.
The *_nv() variants of these functions return the new value of target.
No errors are defined.

The *_nv() variants are substantially more expensive on some platforms than the versions that do not return values. Do not use them unless you need to know the new value atomically.
