The iterator is not advanced.

This function combines g_menu_link_iter_next() with g_menu_link_iter_get_name() and g_menu_link_iter_get_value().
First the iterator is advanced to the next (possibly first) link. If that fails, then false
is returned and there are no other effects.
If successful, out_link and value are set to the name and MenuModel of the link that has just been advanced to. At this point, g_menu_link_iter_get_name() and g_menu_link_iter_get_value() will return the same values again.
The value returned in out_link remains valid for as long as the iterator remains at the current position. The value returned in value must be unreffed using Glib::object_unref() when it is no longer in use.
out_link | The name of the link. |
value | The linked MenuModel. |

on success, or false

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.
bool Gio::MenuLinkIter::next | ( | ) |
Attempts to advance the iterator to the next (possibly first) link.
true
is returned on success, or false
if there are no more links.
You must call this function when you first acquire the iterator to advance it to the first link (and determine if the first link exists at all).
true
on success, or false
when there are no more links. Glib::RefPtr< Gio::MenuLinkIter > wrap | ( | GMenuLinkIter * | object, |

) | [related] |
A Glib::wrap() method for this object.
object | The C instance. |
take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |
