_memicmp

Visual Studio .NET 2003

Compares characters in two buffers (case-insensitive).

int _memicmp(
   const void *buf1,
   const void *buf2,
   size_t count 
);

Parameters

buf1: First buffer.
buf2: Second buffer.
count: Number of characters.

Return Value

The return value indicates the relationship between the buffers.

Return value	Relationship of first count bytes of buf1 and buf2
< 0	buf1 less than buf2
0	buf1 identical to buf2
> 0	buf1 greater than buf2

Remarks

The _memicmp function compares the first count characters of the two buffers buf1 and buf2 byte by byte. The comparison is not case sensitive.

Requirements

Routine	Required header	Compatibility
_memicmp	<memory.h> or <string.h>	Win 98, Win Me, Win NT, Win 2000, Win XP

For additional compatibility information, see Compatibility in the Introduction.

Libraries

All versions of the C run-time libraries.

Example

// crt_memicmp.c
/* This program uses _memicmp to compare
 * the first 29 letters of the strings named first and
 * second without regard to the case of the letters.
 */

#include <memory.h>
#include <stdio.h>
#include <string.h>

int main( void )
{
   int result;
   char first[] = "Those Who Will Not Learn from History";
   char second[] = "THOSE WHO WILL NOT LEARN FROM their mistakes";
   /* Note that the 29th character is right here ^ */

   printf( "Compare '%.29s' to '%.29s'\n", first, second );
   result = _memicmp( first, second, 29 );
   if( result < 0 )
      printf( "First is less than second.\n" );
   else if( result == 0 )
      printf( "First is equal to second.\n" );
   else if( result > 0 )
      printf( "First is greater than second.\n" );
}

Output

Compare 'Those Who Will Not Learn from' to 'THOSE WHO WILL NOT LEARN FROM'
First is equal to second.
