For the second call to ftruncate(), redefine MY_MAX.  My HD has 320MB
free, so it should fail at 400

#include <stdio.h>
#include <unistd.h>
#include <io.h>

#define MY_MAX 400

int main( int argc, char *argv[] )
{
  int h = _creat( "testtr.fil", 0 );
  printf( "file len : %ld\n", filelength( h ) );
  printf( "ftruncate: %d\n", ftruncate( h, 1024 * 1024 ) );
  printf( "file len : %ld\n", filelength( h ) );
  printf( "ftruncate: %d\n", ftruncate( h, 1024 * 1024 * MY_MAX ) );
  printf( "file len : %ld\n", filelength( h ) );
  _close( h );
  return 0;
}
