     void
     ck_pr_neg_64(uint64_t *target);

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

     void

     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.
