_memicmp

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.
