19* _mbsicoll - Collate MBCS strings, ignoring case
20*
21*Purpose:
22* Collates two strings for lexical order (ignoring case).
23* Strings are collated on a character basis, not a byte basis.
24*
25*Entry:
26* char *s1, *s2 = strings to collate
27*
28*Exit:
29* Returns <0 if s1 < s2
30* Returns 0 if s1 == s2
31* Returns >0 if s1 > s2
32* Returns _NLSCMPERROR is something went wrong
33*
34*Exceptions:
35* Input parameters are validated. Refer to the validation section of the function.
