<p>Greetings,</p><p>I'm wondering what exactly sets off the socket_data function in wayland/wayland-server.c at approximate line 640. I can see that we add a file descriptor object of our socket to the main loop in wl_display_add_socket that uses socket_data as the callback function when a client connects to that socket. Subsequently, we accept the connection in socket_data and create a new client.</p>
<p>So, what is it in client's code that causes socket_data to be called? Is it just the mere connect() call to establish a connection through that socket or is it anything more complex that I have missed?</p><p>My knowledge of sockets is quite basic, so I would be happy if someone would clarify how exactly this bit of code is executed.</p>
