Re: Problems with IO::Select

Try printing $! after the call to can_read. select should set it.

Speaking of error checking,
$client->{socket} = IO::Socket::UNIX->new(...);
should be
$client->{socket} = IO::Socket::UNIX->new(...)
or die("Unable to open socket: $!\n");

Thanks for the info. Putting print $! directly after the while statement produced nothing, so I added an END block to the code and put print $! in it. The only thing printed was "Interrupted System Call" which still leaves me not knowing what the heck is going on with it, but hopefully tells one of you gurus what I'm doing wrong.	[reply]

That message is from something that happened between the `while` and the `END` — possibly something internal — not something from the `select`. That `$!` is blank seems to indicate the `select` succeeded (for some definition of succeeded), or `$r` wasn't defined. I personally don't know anything about unix sockets. Maybe they are different from IP sockets in some important manner for `select`. I don't think I'll be of any more use to you.	[reply] [d/l] [select]
