SYNOPSIS

       #include <ck_pr.h>

       void *
       ck_pr_fas_ptr(void *target, void *new_value);

       double
       ck_pr_fas_double(double *target, double new_value);

       char
       ck_pr_fas_char(char *target, char new_value);

       unsigned int
       ck_pr_fas_uint(unsigned int *target, unsigned int new_value);

       int
       ck_pr_fas_int(int *target, int new_value);

       uint64_t
       ck_pr_fas_64(uint64_t *target, uint64_t new_value);

       uint32_t
       ck_pr_fas_32(uint32_t *target, uint32_t new_value);

       uint16_t
       ck_pr_fas_16(uint16_t *target, uint16_t new_value);

       uint8_t
       ck_pr_fas_8(uint8_t *target, uint8_t new_value);

DESCRIPTION

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

RETURN VALUES

       This  function  returns  the value pointed to by target at the time of operation invocation before it was
       atomically replaced with new_value.
