SYNOPSIS

       #include <ck_pr.h>

       uintptr_t
       ck_pr_faa_ptr(void *target, uintptr_t delta);

       double
       ck_pr_faa_double(double *target, double delta);

       char
       ck_pr_faa_char(char *target, char delta);

       unsigned int
       ck_pr_faa_uint(unsigned int *target, unsigned int delta);

       int
       ck_pr_faa_int(int *target, int delta);

       uint64_t
       ck_pr_faa_64(uint64_t *target, uint64_t delta);

       uint32_t
       ck_pr_faa_32(uint32_t *target, uint32_t delta);

       uint16_t
       ck_pr_faa_16(uint16_t *target, uint16_t delta);

       uint8_t
       ck_pr_faa_8(uint8_t *target, uint8_t delta);

DESCRIPTION

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

RETURN VALUES

       This  function  returns  the  value  pointed  to by target at the time of operation invocation before the
       addition operation is applied.
