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;
}
}
