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.
