Re^4: Problem with IO::Select

Ah, ok. So I changed it to

my $rx_txt = "something";
while (length($rx_txt) > 0) {
  $conn->recv($rx_txt, 1024);
  $buff.=$rx_txt;
}
[download]

But the problem stays the same.

You probably meant to write: `while ($rh->recv($rx_txt, 1024) > 0) { $buff .= $rx_txt; }` [download] But that's not good code when using 'select'. That's only okay if you're only handling one connection at a time. If you're only handling one connection at a time, don't use select. Also, I hope you know that adding a file handle for "~/.somefile" only makes sense if it's a fifo (named pipe). There are actually a lot of problems with your code. You should probably look at something somebody else has written. I recommend The Perl Cookbook, although there are a lot of free examples scattered about the internet.	[reply] [d/l]
Re^5: Problem with IO::Select (won't block) by tye (Sage) on Mar 01, 2007 at 01:26 UTC
"can_read" really means "trying to read won't block", which means that end-of-file will cause can_read to keep returning "true" forever. That might be your problem. You need to detect end-of-file and then (probably) close the socket and stop asking if you can read from it. - tye	[reply]
