Macro Definition Documentation

NON_ZERO

#define NON_ZERO

(

_x

)

(1 + sizeof(struct { char size[(_x)-1]; }))

Returns

_x so that it can be used as a compile time known value

same_type

#define same_type	(		_a,
			_b
	)		__builtin_types_compatible_p(typeof(_a), typeof(_b))

Note that 'unsigned int' and 'int' return false in this case.
