16*int _stricoll() - Collate locale strings without regard to case
17*
18*Purpose:
19* Compare two strings using the locale LC_COLLATE information
20* without regard to case.
21*
22*Entry:
23* const char *s1 = pointer to the first string
24* const char *s2 = pointer to the second string
25*
26*Exit:
27* Less than 0 = first string less than second string
28* 0 = strings are equal
29* Greater than 0 = first string greater than second string
30* Returns _NLSCMPERROR is something went wrong

32*Exceptions:
33* Input parameters are validated. Refer to the validation section of the function.
