     uint32_t atomic_add_32_nv(volatile uint32_t *target, int32_t delta);

DESCRIPTION
     These functions enable the addition of delta  to  the  value
     stored in target to occur in an atomic manner.

RETURN VALUES
     The *_nv() variants of these functions return the new  value
     of target.

ERRORS
     No errors are defined.

ATTRIBUTES
     See attributes(5) for descriptions of the  following  attri-
     butes:

NOTES
     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  atomi-
     cally  (for example, when decrementing a reference count and
