Usage of Utime() function -urgent

pls give me an example of utime funtion to set the file modification time.
when i used this with null parameter it does not change the file modification time to the current time

From MSDN:


/* UTIME.C: This program uses _utime to set the
* file-modification time to the current time.
*/

#include <stdio.h>
#include <stdlib.h>
#include <sys/types.h>
#include <sys/utime.h>

void main( void )
{
/* Show file time before and after. */
system( "dir utime.c" );
if( _utime( "utime.c", NULL ) == -1 )
perror( "_utime failed\n" );
else
printf( "File time modified\n" );
system( "dir utime.c" );
}





Output

Volume in drive C is ALDONS
Volume Serial Number is 0E17-1702

Directory of C:\dolphin\crt\code

05/03/94 10:00p 451 utime.c
