[dbus-cplusplus-devel] Calling DeviceKit methods

[Zoltan B. <zol...@gm...>]

Hello All,

I'm trying to mount and unmount devices through dbus-c++ binding,
using DeviceKit.Disks.Device interface methods.
While trying to unmount device, I get a 'SIGTRAP' signal.
Can anybody show me what I'm doing wrong in this code?

Thanks, any help is very appreciated.


// Proxy implementation
DisksDeviceProxy::DisksDeviceProxy(DBus::Connection &connection, const
char *object_path)
: DBus::InterfaceProxy("org.freedesktop.DeviceKit.Disks"),
  DBus::ObjectProxy(connection, object_path,
"org.freedesktop.DeviceKit.Disks.Device")
{
}

// Mount device
void DisksDeviceProxy::MountDevice(const char *fstype,
std::vector<std::string> &options)
{
	::DBus::CallMessage call;
	::DBus::MessageIter wi = call.writer();

	wi << fstype;
	wi << options;
	call.member("FilesystemMount");
	::DBus::Message ret = invoke_method (call);
	::DBus::MessageIter ri = ret.reader();
}

// Unmount device
void DisksDeviceProxy::UnMountDevice(std::vector<std::string> &options)
{
	::DBus::CallMessage call;
	::DBus::MessageIter wi = call.writer();

	wi << options;
	call.member("FilesystemUnmount");
	::DBus::Message ret = invoke_method (call); // Signaled SIGTRAP right here
	::DBus::MessageIter ri = ret.reader();
}

And here is the code, how I'm trying to unmount device:
//-- START
DBus::BusDispatcher dispatcher;
DBus::default_dispatcher = &dispatcher;

DBus::Connection conn = DBus::Connection::SystemBus();

DisksDeviceProxy devkit(conn,
"/org/freedesktop/DeviceKit/Disks/devices/sdb1"); // for now, just
hard coded value of my USB device
std::vector<std::string>options;
devkit.UnMountDevice(options);
//-- END
