Function Documentation

int th_wcstrcoll	(	const thwchar_t *	s1,
		const thwchar_t *	s2
	)

Compare two Thai wide-char strings for collation.

Parameters:

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

Returns:

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

size_t th_wcstrxfrm	(	thwchar_t	dest[],
		const thwchar_t *	src,
		size_t	n
	)

Transform wide-char string into collatable form.

Parameters:

	dest	: the destination wide-char string buffer
	src	: the wide-char string to transform
	n	: the size of dest buffer (as number of elements)

Returns:

the number of elements 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 wcscmp() yields the same result as that from th_wcstrcoll(). At most n characters are put in dest.
