Hi, <div class="gmail_quote"> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi, I can send a struct through a signal with the help of some members of the list, now i have another question, how can i get this struct when reveice get this signal?</blockquote><div> -- Well its a bit complicated with the low level apis, I mean you need to attach a iterator with the message, and then recurse through the arguments to get the value.i.e if in the message you have a struct of string and int as s(su) then i will be like: dbus_message_iter_init(message, &iter); dbus_message_iter_recurse(&iter, &iter1); /* To go inside the struct */ while (dbus_message_iter_get_arg_type(&iter1) != DBUS_TYPE_INVALID) { dbus_message_iter_get_basic(iter, &value); dbus_message_iter_next(iter); } -- Hope this will give you some idea.. -Br Naveen </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Brenno Em Qua, 2009-02-18 às 19:21 -0500, Havoc Pennington escreveu: > Hi, > > On Wed, Feb 18, 2009 at 1:08 PM, Brenno Freire <<a href="mailto:brenno.freire@fucapi.br">brenno.freire@fucapi.br</a>> wrote: > > Got the following error.
