Too lazy to check return values?

Feeling lazy?  Carpel tunnel got you down?  Just don't feel like typing all this?

  if ( unlink("filename") == -1 ) {
       diehorribly();
  }
  if ( (bytes = read( fd, buffer, 100 )) < 0  )  {
       diehorribly();
  }
  if ( ( fd = open( FILENAME, O_RDWR|O_EXCL|O_CREAT, 0666 ) ) == 0 ) {
       diehorribly();
  }
