SYNOPSIS
       #include	<ck_pr.h>

       ck_pr_neg_ptr(void *target);

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

       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

       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  re-
       sult  of	the negation operation was 0. They set the pointed to value to
       false otherwise.
