sockets help??
Hello, Just wondering if you could give me a hand with sockets? If not I understand. I am trying to write winsock software to have one client connect to three different server computers (not simultaneously) by simple sock stream. I tried to create one socket and connect to each computer. Once the previous connection is completed with one of the computers, I would change the last part of the IP to connect to another computer, but with the same socket. I used the same port for all connections. It did not work. Any suggestions? When I use closesocket() function, does that make that socket unusable? After you connect to a server computer, then leave continue doing something else, is the connection still live? Thanx! Raymond

I don't know the winsock implemantation...but:
When you close the socket, you destroy the socket descriptor = you must
create a new socket descriptor, for examle:
sub net{
socket(SO,PF_INET,SOCK_STREAM,getprotobyname('tcp')) || die$!\n;
my $ip=$_[0];
my $port=$_[1];
my $dest=sockaddr_in($port,inet_aton($ip));
if(connect(SO,$dest)){
###your client code ###
close(SO);
return 1;
}
else{
close(SO);
return 0;
}
}

It can already do this out of the box, it's very easy to use, and it doesn't require any knowlege of sockets. Walt -- Walter C.
