Detailed Description

Thai wide-char string collation.


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.
