Detailed Description

Comparator function prototypes.

Comparator functions of the type kzInt compare(const void* first, const void* second) which returns 0 if first == second, negative number if first < second and positive if first > second. For integer values the comparator can be implemented simply as return first - second; to get natural ordering from small to large.

Typedef Documentation

typedef kzInt(* KzcComparatorWithContextFunction)(const void *first, const void *second, const void *context)

Comparator function with arbitrary context.

Same as KzcComparatorFunction with additional context parameter.

Function Documentation

kzInt kzcCompareInts	(	const void *	first,
		const void *	second
	)

Comparator function for signed integers.

kzInt kzcCompareU32s	(	const void *	first,
		const void *	second
	)

Comparator function for unsigned 32 bit integers.

kzInt kzcCompareFloats	(	const void *	first,
		const void *	second
	)

Comparator function for floating points.

kzInt kzcComparePointers	(	const void *	first,
		const void *	second
	)

Comparator function for pointers.

kzInt kzcCompareStrings	(	const void *	first,
		const void *	second
	)

Comparator function for strings.

Variable Documentation

KZ_HEADER_BEGIN typedef kzInt(* KzcComparatorFunction)(const void *first, const void *second)

Comparator function.

Returns negative integer if first < second, 0 if they are equal and positive integer if first > second. Note that the comparator must return 0 whenever first == second.
