Error Callback

The "error" callback handles errors which might occur while executing the libdmapsharing mainloop. The parameters are a DmapConnection, GError, and pointer to user data.

The following is a simple "error" callback:

static void
error_cb(DmapConnection *connection, GError *error, gpointer user_data)
{
	fprintf(stderr, "%s\n", error->message);
}
