DESCRIPTION

42     The ck_pr_faa(3) family of functions atomically fetch the value pointed
43     to by target and add the value specified by delta to the value pointed to
44     by target.
45

RETURN VALUES

47     This function returns the value pointed to by target at the time of oper‐
48     ation invocation before the addition operation is applied.
