I'm quite new to network programming under Unix and I'm developping a
server that acts as a kind of «gateway» between a client (written in
Flash and using ActionScript) and a database (PostGreSQL).
The client sends XML streams to the server and the latter parses and
analyzes the streams. It then contacts the database in order to do
It really is a classical schema.
The server must handle multiple connections at a time, so I've decided
to user a GServer structure to implement it. I'm keeping a reference of
each new GConn that it handles in a list.
My questions are :
1) I want to use threads for each new connection, that is, the server is
asynchronous (GServer makes asynchronous I/O, does it ?) and everytime
there's a new connection, I start a new thread and do the necessary job
for this connection. Is it the right way to handle multiple connections
in a threaded app ?
2) Sometimes (not always), I have to send a message back to one or more
connections (that's why I keep reference to them). I've seen that there
is a function named «gnet_conn_set_watch_writable ()» to watch if data
can be send to the socket. How do I use this ? Must I also set a
callback for the GNET_CONN_WRITABLE event ? I see it like this :
gnet_conn_set_callback (connection, my_callback, my_datas);
Is it correct ?
