Re: [sigc] Socket library using libsigc++?

[Aaron Griffin <aaronmgriffin gmail com>]

Hmmm if you're interested in doing it youself, you can make something
like so (assuming it has access to the socket file descriptors):

NOTE: this may not work... I haven't tested it - it's just an example
to show you how easy it is to detect these things.

fd_set socks;
MyClientSocket cl("http://www.google.com",8080);
MyServerSocket srv(1234);

FD_ZERO(socks);
FD_SET(cl.descriptor(),socks);
FD_SET(srv.descriptor(),socks);

timeval tv;
tv.tv_sec = 1;
tv.tv_usec = 0;
int i = select(FD_SETSIZE,&socks,0,0,&tv);

if(i == 0) {} // timeout occured (1sec)
else if(i > 0) // i sockets are readable
{
   //client readable indicates incoming data
   if(FD_ISSET(cl.descriptor(),socks)) { /*emit*/ }
   //server readable indicates incoming connection
   if(FD_ISSET(srv.descriptor(),socks)) { /*emit*/ }
}
else { /*error*/ }
