SYNOPSIS
     #include <ck_pr.h>

     void
     ck_pr_neg_ptr(void *target);

     void
     ck_pr_neg_ptr_zero(void *target, bool *z);

     void
     ck_pr_neg_double(double *target);

     void
     ck_pr_neg_double_zero(double *target, bool *z);

     void
     ck_pr_neg_char(char *target);

     void
     ck_pr_neg_char_zero(char *target, bool *z);

     void
     ck_pr_neg_uint(unsigned int *target);

     void
     ck_pr_neg_uint_zero(unsigned int *target, bool *z);

     void
     ck_pr_neg_int(int *target);

     void
     ck_pr_neg_int_zero(int *target, bool *z);

     void
     ck_pr_neg_64(uint64_t *target);

     void
     ck_pr_neg_64_zero(uint64_t *target, bool *z);

     void
     ck_pr_neg_32(uint32_t *target);

     void
     ck_pr_neg_32_zero(uint32_t *target, bool *z);

     void
     ck_pr_neg_16(uint16_t *target);

     void
     ck_pr_neg_16_zero(uint16_t *target, bool *z);

     void
     ck_pr_neg_8(uint8_t *target);

     void
     ck_pr_neg_8_zero(uint8_t *target, bool *z);

DESCRIPTION
     The ck_pr_neg(3) family of functions atomically negate the value pointed
     to by target.

RETURN VALUES
     The ck_pr_neg_zero functions set the value pointed to by z if the result
     of the negation operation was 0. They set the pointed to value to false
     otherwise.
