Macro Definition Documentation

ae2f_Macro_Cmp_Diff

#define ae2f_Macro_Cmp_Diff	(		a,
			b )

Value:

(ae2f_Macro_Cmp_TakeGt(a, b) - ae2f_Macro_Cmp_TakeLs(a, b))

Returns

The absolute different of two.

ae2f_Macro_Cmp_TakeGt

#define ae2f_Macro_Cmp_TakeGt	(		a,
			b )

Value:

((a) > (b) ? (a) : (b))

Warning

Two parameters must be comparable with operator.

Returns

One bigger.

ae2f_Macro_Cmp_TakeLs

#define ae2f_Macro_Cmp_TakeLs	(		a,
			b )

Value:

((a) < (b) ? (a) : (b))

Warning

Two parameters must be comparable with operator.

Returns

One smaller.

ae2f_Macro_Cmp_TakeMem

#define ae2f_Macro_Cmp_TakeMem	(		ptr,
			member,
			alter )

Value:

((ptr) ? ((ptr)->member) : (alter))

Gets the member from the pointer. Given nullptr, the return will be alter.

Parameters

ptr	The pointer for getting member.
member	The valid member's name. [from the structure]
alter	The alternative value when given nullptr.

ae2f_Macro_Cmp_TakeSelf

#define ae2f_Macro_Cmp_TakeSelf	(		ptr,
			alt )

Value:

((ptr) ? (ptr) : (alt))

Returns ptr's self. Given nullptr, the return will be alt.

Parameters

ptr	Self Referring
alt	The alternative value.
