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.

   else if( result < 0 )
      _mbscpy( tmp, "less than" );

   printf( "Function:\t_mbsnicmp _mbsnicmp (first 10 characters only)\n" );
   result = _mbsnicmp( string1, string2, 10 );

      _mbscpy( tmp, "greater than" );
   else if( result < 0 )
      _mbscpy( tmp, "less than" );

}

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
