From a0cc21f8bb6752ffe0ee5f4f5b575dc50d6d46ae Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Wed, 22 Apr 2009 03:41:05 +0200 Subject: unix-fd: add message encoding/decoding for unix fds When appending unix fds to the message a new entry in the fd array will be allocated and the index to it will be written to the message payload. When parsing unix fds from the message the index will be read from the payload and then looked up in the fd array. When we read fds we put them in a queue first. Since each message knows how many fds are attached to it we will then pop enough fds from this queue each time we decode a message from the stream. This should make sending and receiving more portable since we don't make any strong requirements on the exact semantics of the SCM_RIGHTS implementation: as long as fds are recieved in order, none or lost and the arrive at the same time as at least one byte from the actual message dat we should be able to handle them correctly. --- dbus/dbus-transport.h | 2 ++ 1 file changed, 2 insertions(+) (limited to 'dbus/dbus-transport.h') diff --git a/dbus/dbus-transport.h b/dbus/dbus-transport.h index 691763ca..4554faf3 100644 --- a/dbus/dbus-transport.h +++ b/dbus/dbus-transport.h @@ -40,6 +40,8 @@ void _dbus_transport_disconnect (DBusTransport dbus_bool_t _dbus_transport_get_is_connected (DBusTransport *transport); dbus_bool_t _dbus_transport_get_is_authenticated (DBusTransport *transport); dbus_bool_t _dbus_transport_get_is_anonymous (DBusTransport *transport); +dbus_bool_t _dbus_transport_can_pass_unix_fd (DBusTransport *transport); + const char* _dbus_transport_get_address (DBusTransport *transport); const char* _dbus_transport_get_server_id (DBusTransport *transport); dbus_bool_t _dbus_transport_handle_watch (DBusTransport *transport, -- cgit
