Re: [PLUG] Linux FIFOs

[Eric Lucas <eric@lucii.org>]

I know why I don't write an EOF... I close the file handle.
That takes care of it for me :-P

Here is my write loop:

while (1) {
   open (FIFO, "> $FIFO") or die "ERROR: can't write fifo $FIFO $!" ;
   printf FIFO "$IdentString" ;    # preformatted "signature"
   printf FIFO "="x72 . "\n$quote[$ix]" ;  # actual quote
   close FIFO ;
   if ( $ix++ > ($count - 2)) { 
      $ix = 0 ; 
   } 
   sleep(1) ;
}


I step through the list rather than select randomly.  Hence, the $ix++
