in reply to built-in socket functions

What kind of socket do you have?

Doesn't SO_SNDTIMEO require blocking sockets?

Why aren't you error checking?

setsockopt ... or die Fudge("SO_SNDTIMEO"); setsockopt ... or die Fudge("SO_RCVTIMEO"); sub Fudge { use Errno(); join qq/\n/, "Error @_", map { " $_" } int( $! ) . q/ / . $!, int( $^E ) . q/ / . $^E, grep( { $!{$_} } keys %! ), q/ /; }

    I tried errorchecking but no error, doesn't even seem to matter what i write after pack().I have something like:

    $port=80; $proto=getprotobyname('tcp'); socket(SOCKET,AF_INET,SOCK_STREAM,$proto) or die "no socket"; setsockopt(SOCKET,SOL_SOCKET,SO_RCVTIMEO,pack("LL",1,0)); $iadr = inet_aton("127.0.0.1"); $padr=sockaddr_in($port,$iadr); if(connect(SOCKET,$padr)){ print "connection ok";} else{print "$!\n";}

    It should correspond to something like:

    $conn = IO::Socket::INET->new( PeerAddr=>"127.0.0.1", PeerPort=>80, Proto=>'tcp', Timeout=> 1, Blocking=>1 );

    So: a blocking socket with a 1 second timeout because now the standardtimeout is something like 10 seconds,making my applications run slower iso faster which was the general idea.

      See Re: how to set socket recv timeout in architecture independent manner?

        I allready looked at that, says on windows SO_RCVTIMEO is considered to be a DWORD, but i cannot find any documentation on how to pack a DWORD, so i keep getting stuck. I thought maybe it would be something simple, cause it doesn't take much effort if you're using the IO::Socket module. But nevermind, I'll work something out. Thank you.
