DESCRIPTION

42     The ck_pr_fas(3) family of functions atomically fetch the value pointed
43     to by target and replace the value pointed to by target with the value
44     specified by new_value.
45

RETURN VALUES

47     This function returns the value pointed to by target at the time of oper‐
48     ation invocation before it was atomically replaced with new_value.
