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

DESCRIPTION

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