Detailed Description

Thai string collation.

Function Documentation

int th_strcoll	(	const thchar_t *	s1,
		const thchar_t *	s2
	)

Compare two Thai strings for collation.

Parameters

s1	: first string (null-terminated)
s2	: second string (null-terminated)

Returns

< 0 if s1 precedes s2; 0 if s1 equals s2; > 0 if s1 succeeds s2

size_t th_strxfrm	(	thchar_t	dest[],
		const thchar_t *	src,
		size_t	n
	)

Transform string into collatable form.

Parameters

dest	: the destination string buffer
src	: the string to transform
n	: the size of dest buffer

Returns

the number of bytes required to store the result in dest, excluding the terminating '\0'. If the return value >= n, dest is undefined.

Transforms src into a form from which comparison using strcmp() yields the same result as that from th_strcoll(). At most n characters are put in dest.
