_mbsnbcmp

Visual Studio 6.0

int _mbsnbcmp( const unsigned char *string1, const unsigned char string2, size_t count );

Routine Required Header Compatibility
_mbsnbcmp <mbstring.h> Win 95, Win NT

For additional compatibility information, see Compatibility in the Introduction.

Libraries

LIBC.LIB Single thread static library, retail version
LIBCMT.LIB Multithread static library, retail version
MSVCRT.LIB Import library for MSVCRT.DLL, retail version

Return Value

The return value indicates the relation of the substrings of string1 and string.

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

Strings to compare

count

Number of bytes to compare

Remarks

The _mbsnbcmp function lexicographically compares, at most, the first count bytes in string1 and string2 and returns a value indicating the relationship between the substrings. _mbsnbcmp is a case-sensitive version of _mbsnbicmp. Unlike strcoll, _mbsnbcmp is not affected by locale. _mbsnbcmp recognizes multibyte-character sequences according to the current multibyte code page.

_mbsnbcmp is similar to _mbsncmp, except that _mbsnbcmp compares strings by characters rather than by bytes.

Example

/* STRNBCMP.C */
#include <mbstring.h>

char string1[] = "The quick brown dog jumps over the lazy fox";

void main( void )

   char tmp[20];
   int result;
   printf( "Compare strings:\n\t\t%s\n\t\t%s\n\n", string1, string2 );
   printf( "Function:\t_mbsnbcmp (first 10 characters only)\n" );
   result = _mbsncmp( string1, string2 , 10 );
   if( result > 0 )
      _mbscpy( tmp, "greater than" );
   else if( result < 0 )
      _mbscpy( tmp, "less than" );
   else
      _mbscpy( tmp, "equal to" );
   printf( "Result:\t\tString 1 is %s string 2\n\n", tmp );
   printf( "Function:\t_mbsnicmp _mbsnicmp (first 10 characters only)\n" );
   result = _mbsnicmp( string1, string2, 10 );
   if( result > 0 )
      _mbscpy( tmp, "greater than" );
   else if( result < 0 )
      _mbscpy( tmp, "less than" );
   else
      _mbscpy( tmp, "equal to" );
   printf( "Result:\t\tString 1 is %s string 2\n\n", tmp );
}

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
