Detailed Description

Macro Definition Documentation

#define ZB_ASSERT_COMPILE_DECL ( expr )

Check condition at compile time in the declaration block

Parameters

expr	- expression to check.

#define ZB_ASSERT_COMPILE_TIME ( expr ) ((void)(zb_int_t (*)[(expr) ? 1 : -1])0)

Check condition at compile time in the code (not declaration block)

Parameters

expr	- expression to check.

#define ZB_ASSERT_COMPILE_TIME_EXPR ( expr ) ((zb_int_t)((zb_int_t (*)[(expr) ? 1 : -1])0))

Check condition at compile time in the code (not declaration block), return 0 To be used inside an expressions.

Parameters

expr	- expression to check.

#define ZB_ASSERT_TYPE_SIZE_EQ	(	type,
		limit
	)	ZB_ASSERT_COMPILE_DECL(sizeof(type) == (limit))

Ensures, that size of type `type' is equal to the `limit'. If it is not, compilation is aborted.

Parameters

type	- type name
limit	- size limit

#define ZB_ASSERT_TYPE_SIZE_NOT_GREATER	(	type,
		limit
	)	ZB_ASSERT_COMPILE_DECL(sizeof(type) <= (limit))

Ensures, that size of type `type' is not greater than `limit'. If it is not, compilation is aborted.

Parameters

type	- type name
limit	- size limit

#define ZB_ASSERT_TYPE_SIZE_NOT_LESS	(	type,
		limit
	)	ZB_ASSERT_COMPILE_DECL(sizeof(type) >= (limit))

Ensures, that size of type `type' is not less than `limit'. If it is not, compilation is aborted.

Parameters

type	- type name
limit	- size limit
