Macro Definition Documentation

_SIZEOF_PTR

#define _SIZEOF_PTR   4

bytes = sizeof(void*) for __DECL_ALIGN macro. Can't do sizeof(x). uintptr_t

_sizeofm

#define _sizeofm	(		s,
			m
	)		sizeof(((s *)0)->m)

size_t of a structure member/field (like offsetof()) nullptr

IS_INDEX_BAD

#define IS_INDEX_BAD	(		i,
			q
	)		((COUNT_t)(i)>=(COUNT_t)(q))

cast the (likely) int to unsigned to check for negatives.

IS_INDEX_BAD_ARRAY

#define IS_INDEX_BAD_ARRAY	(		i,
			a
	)		IS_INDEX_BAD(i,_countof(a))

IS_INDEX_GOOD

#define IS_INDEX_GOOD	(		i,
			q
	)		((COUNT_t)(i)<(COUNT_t)(q))

cast the (likely) int to unsigned to check for negatives.

IS_INDEX_GOOD_ARRAY

#define IS_INDEX_GOOD_ARRAY	(		i,
			a
	)		IS_INDEX_GOOD(i,_countof(a))
