+``HX_socket_from_env``
+	The function looks up the current process's file descriptors for a
+	socket that is listening and which matches the given addrinfo and
+	(optionally) intf if the latter is not NULL``. Upon success, the fd
+	number is returned, or -1 if no file descriptor matched. No errors are
+	signalled.
