Mounting samba share in C++ using Giomm

[Szőke Szabolcs <szabolcsx95 gmail com>]

Hi list. I need to mount a samba share in ubuntu as non-sudo user. O found a tool (gvfs-mount) which could do the job. Based on it's source code I wrote a very basic
code in C++, but I get some errors.

Here is the source code:

#include <gtkmm.h>

#include <iostream>

Glib::RefPtr<Gio::File> file;
Glib::RefPtr<Glib::MainLoop> main_loop;

void on_async_ready(Glib::RefPtr<Gio::AsyncResult>& result)
{
    file->mount_enclosing_volume_finish(result);

    main_loop->quit();
}

int main()
{
    Gio::init();
    Glib::init();

    main_loop = Glib::MainLoop::create(false);

    file = Gio::File::create_for_commandline_arg("smb://192.168.1.3/Memory\\ core");
    Glib::RefPtr<Gio::MountOperation> mount_operation = Gio::MountOperation::create();
    mount_operation->set_domain("domain");
    mount_operation->set_username("user");
    mount_operation->set_password("password");

    try
    {
        file->mount_enclosing_volume(mount_operation, &on_async_ready);
    }
    catch(const Glib::Error& ex)
    {
        std::cerr << ex.what() << std::endl;
    }

    main_loop->run();

    return 0;
}

The problem is that when I run this code as normal user I get this output:

(process:5816): glibmm-CRITICAL **: unhandled exception (type Glib::Error) in signal handler: domain: g-io-error-quark code : 0 what : Failed to mount Windows share: Operation not permitted

When I run as sudo I get this:

(process:5862): glibmm-CRITICAL **: unhandled exception (type Glib::Error) in signal handler: domain: g-io-error-quark code : 15 what : volume doesn't implement mount

If I run the gvfs-mount with the same uri which is in source, after I enter the domain, username and password, the shared folder gets mounted. Any help would be appreciated.
