Hi,
I would like to create a new module. This module has to read an external file descriptor and call a callback. I don't want to use extra process and shared memory or something like that.
Is it possible to add FD in the main Select and call my callback ?
Regards,

Execute the callback when something comes on FD?

select is used only for tcp (tls), otherwise is simple read from upd socket. You have to create an extra process.

I have a FD from a socket. If a SIP message comes, it writes on the FD. But I don't wait for the response. I have to be notified of a response on this socket. Is it possible to add a fd and a callback in an internal polling process without a fork (I want to avoid problems of communication between original process and the child) ?

it is not possible. You can look at xmpp module for an similar example of what you need.
