How to Truncate Windows file to zero Size?

Deleting (or) Truncating a Windows File to zero size (especially when the file is in use) is not an easy task in Windows. One will have to close the application (which is using the file), modify the file and then restart the application again.

Just to make this boring task simpler, I have written a c program that will truncate windows file to zero size, even if the file is being used by some other application.

Nothing complex in this code, I have used the "_O_WRONLY | O_TRUNC" options to open the file, which will set the file size to zero.

The absolute path of the File, should be given as the argument to the program.

int main(int argc, char* argv[])
{
    if(argc>1)
    {
         int fileHandler;
         fileHandler = _open( argv[1], _O_WRONLY | O_TRUNC );
         if( fileHandler == -1 )
         {
              printf( "\nOPERATION FAILED\n" );
         }
         else
         {
              printf( "\nOPERATION SUCCESS\n" );
              _close( fileHandler );
         }
    }
}
