_mbsnbcmp

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

For additional compatibility information, see Compatibility in the Introduction.

Return Value

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

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>
#include <stdio.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
