DESCRIPTION

These functions enable the incrementing (by one) of 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(7) for descriptions of the following attributes:

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 atomically.
