in thread IO::Select - reading multiple lines

is it a very worse idea to use <$fh> to read from a socket

Yeah, you are best off using sysread, and there are a few ways to use sysread, depending on your situation, you can put it in various staement forms

while( sysread $fh, $str, 8192, length $str ) { #or do { $rc = sysread(FH, $buff, 5000000, length($buff)) ; } while ($rc #or if ( sysread( $cli, $buffer, 1024 ) ) {} # etc etc

I'm not really a human, but I play one on earth.

    sysread returns 0, only when the other end exits. Getting into blocking mode, which is not desired. I expect the program to wait in select not in sysread.

[1nickt]: If 1nickt is the some guy, that's not what he said.
[GotToBTru]: thepkd might not know about last hour of cb
[1nickt]: my $x = $aohoaoh->[0]->{' foo'}->[0]->{'bar' }; should work
[thepkd]: its not $aohoaoh->[0]. its $aohoaoh[0]->{'foo '}. Tried it. Its working. Thnaks
[thepkd]: Hey 1nickt sorry man. What
