/***

* _mbsicoll - Collate MBCS strings, ignoring case
|
||
|
|
*
|
||
|
|
*Purpose:
|
||
|
|
* Collates two strings for lexical order (ignoring case).
|
||
|
|
* Strings are collated on a character basis, not a byte basis.
|
||
|
|
*
|
||
|
|
*Entry:
|
||
|
|
* char *s1, *s2 = strings to collate
|
||
|
|
*
|
||
|
|
*Exit:
|
||
|
|
* Returns <0 if s1 < s2
|
||
|
|
* Returns 0 if s1 == s2
|
||
|
|
* Returns >0 if s1 > s2
|
||
|
|
* Returns _NLSCMPERROR is something went wrong
|
||
|
|
*
|
||
|
|
*Exceptions:
|
||
|
|
* Input parameters are validated. Refer to the validation section of the function.
