/*++
Function:
_wcsnicmp
Compare characters of two strings without regard to case
Return Value
The return value indicates the relationship between the substrings as follows.
Return Value
Description
< 0 string1 substring less than string2 substring
0 string1 substring identical to string2 substring
> 0 string1 substring greater than string2 substring
Parameters
string1, string2 Null-terminated strings to compare
count Number of characters to compare
Remarks
The _strnicmp function lexicographically compares, at most, the first
count characters of string1 and string2. The comparison is performed
without regard to case; _strnicmp is a case-insensitive version of
strncmp. The comparison ends if a terminating null character is
reached in either string before count characters are compared. If the
strings are equal when a terminating null character is reached in
either string before count characters are compared, the shorter string
is lesser.
