Re: g_utf16_to_utf8

Please, how I avoid this leak?

I tried following, without success:

Glib::ustring win_NetworkInterface::get_name()

{
    Glib::RefPtr<gchar> cname (g_utf16_to_utf8(

            (gunichar2*) this->ifinfo.FriendlyName, -1, NULL, NULL, NULL));
    Glib::ustring name(cname);

    return name;
}

2- Has memory leak on method below?
The generated string from g_utf16_to_utf8 must be freed manually, even when
stored in a ustring?

Glib::ustring win_NetworkInterface::get_name()
{
    Glib::ustring name(g_utf16_to_utf8((gunichar2*)
this->ifinfo.FriendlyName,
            -1, NULL, NULL, NULL));
    return name;
}

As per the documentation, g_utf16_to_utf8() return an allocated pointer that must be freeed. Also the pointer can be NULL (and that might be a problem for Glib::ustring).


Glib::ustring never do anything to the pointer it gets passed at construction time.
