ae2f_CmpGetGt

#define ae2f_CmpGetGt	(		a,
			b )

Value:

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

Warning

Warning

Two parameters must be comparable with operator.

Returns

One smaller.

#define ae2f_CmpGetMem	(		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.

Definition at line 87 of file Cmp.h.

ae2f_CmpGetSelf

#define ae2f_CmpGetSelf	(		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.
