Return Value
The return value indicates the relationship between the substrings.
| Return Value | Description |
| < 0 | string1 substring less than string2 substring |
| 0 | string1 substring identical to string2 substring |
| > 0 | string1 substring greater than string2 substring |
On an error, _mbsnbcmp returns _NLSCMPERROR, which is defined in STRING.H and MBSTRING.H.
Parameters
string1, string2
Null-terminated strings to compare
count
Number of bytes to compare
Remarks
The _mbsnbicmp function lexicographically compares, at most, the first count bytes of string1 and string2. The comparison is performed without regard to case; _mbsnbcmp is a case-sensitive version of _mbsnbicmp. 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.
_mbsnbicmp is similar to _mbsnicmp, except that it compares strings by bytes instead of by characters.
Two strings containing characters located between 'Z' and 'a' in the ASCII table ('[', '\', ']', '^', '_', and '`') compare differently, depending on their case. For example, the two strings "ABCDE" and "ABCD^" compare one way if the comparison is lowercase ("abcde" > "abcd^") and the other way ("ABCDE" < "ABCD^") if it is uppercase.
_mbsnbicmp recognizes multibyte-character sequences according to the multibyte code page currently in use. It is not affected by the current locale setting.

Output
Compare strings:
The quick brown dog jumps over the lazy fox
The QUICK brown fox jumps over the lazy dog
Function: _mbsnbcmp (first 10 characters only)
Result: String 1 is greater than string 2
Function: _mbsnicmp (first 10 characters only)
Result: String 1 is equal to string 2
