Here is what I thought about a network component. I imagined one component for 
connecting to a socket as a client, and one other component to let a 
application becoming a server.

As you quickly noticed, Nigel, there is a polling problem. You have a Gambas 
API function named "GB.Watch" that tells the interpreter that he must watch a 
file descriptor. Search "GB_Watch" (yes, with an underscore) in "CProcess.c".

This "client" component will almost be the same as your Socket component.

But the "server" component will be something more sophisticated. It will 
transform a Gambas application into a true TCP/IP server. The programmer will 
just have to specifiy a port number and a protocol. The component will do all 
the polling, all the accept stuff, and will manage each connection in the 
same process (no fork, no thread, the interpreter won't support them). The 
Gambas programmer will have nothing to do. As simple as possible !

I quickly looked your socket component, and there are problems, but it is just 
a lack of information about how to make components.

When the Gambas API documention will be finished, everything will be easier to 
program and understand of course !
