SYNOPSIS

     #include <ck_pr.h>

     void
     ck_pr_sub_ptr(void *target, uintptr_t delta);

     void
     ck_pr_sub_double(double *target, double delta);

     void
     ck_pr_sub_char(char *target, char delta);

     void
     ck_pr_sub_uint(unsigned int *target, unsigned int delta);

     void
     ck_pr_sub_int(int *target, int delta);

     void
     ck_pr_sub_64(uint64_t *target, uint64_t delta);

     void
     ck_pr_sub_32(uint32_t *target, uint32_t delta);

     void
     ck_pr_sub_16(uint16_t *target, uint16_t delta);

     void
     ck_pr_sub_8(uint8_t *target, uint8_t delta);

DESCRIPTION

     The ck_pr_sub(3) family of functions atomically subtract the value specified by delta from
     the value pointed to by target.

RETURN VALUES

     This family of functions does not have a return value.
