I've been playing with libev in D lately, and I've run into a problem.
I've been able to hack around it, but it'd like to find a better, more
general solution. Here's a link to the code:
https://github.com/beatgammit/fun-with-d/blob/master/libev/tcp_server.d
The code is a basic TCP server that responds to connections in a
non-blocking fashion. It's not perfect, and the current problem I'm
trying to solve is how to get my Socket instance (from accept) to the
handler. Since everything is asynchronous, and the return value of
accept() will get lost (garbage collected, I think). When I try to get
the address of it, the compiler complains that it's not an lvalue.
Socket instance returned by accept won't be garbage collected (or lost)
as long as you have a reference to it active somewhere in your program.
It doesn't matter which thread. Just take the return value of accept and
pass it to your handler as is. As long as your handler holds on to the
reference, you're fine. No need to try and get the address, or hack
around it.
