* While GtkApplication works fine with plain #GtkWindows, it is recommended

* To set an application menu on a GtkApplication, use
- * g_application_set_app_menu(). The #GMenuModel that this function
+ * gtk_application_set_app_menu(). The #GMenuModel that this function

+ * GtkApplication optionally registers with a session manager
+ * of the users session (if you set the #GtkApplication:register-session
+ * property) and offers various functionality related to the session
+ * life-cycle.
+ *
+ * An application can block various ways to end the session with
+ * the gtk_application_inhibit() function. Typical use cases for
+ * this kind of inhibiting are long-running, uninterruptible operations,
+ * such as burning a CD or performing a disk backup. The session
+ * manager may not honor the inhibitor, but it can be expected to
+ * inform the user about the negative consequences of ending the
+ * session while inhibitors are present.

+ * gtk_application_inhibit:
+ * @application: the #GApplication
+ * @window: (allow-none): a #GtkWindow, or %NULL
+ * @flags: what types of actions should be inhibited
+ * @reason: (allow-none): a short, human-readable string that explains
+ * why these operations are inhibited
+ *
+ * Inform the session manager that certain types of actions should be
+ * inhibited. This is not guaranteed to work on all platforms and for
+ * all types of actions.
+ *
+ * Applications should invoke this method when they begin an operation
+ * that should not be interrupted, such as creating a CD or DVD. The
+ * types of actions that may be blocked are specified by the @flags
+ * parameter. When the application completes the operation it should
+ * call g_application_uninhibit() to remove the inhibitor. Note that
+ * an application can have multiple inhibitors, and all of the must
+ * be individually removed. Inhibitors are also cleared when the
+ * application exits.
+ *
+ * Applications should not expect that they will always be able to block
+ * the action. In most cases, users will be given the option to force
+ * the action to take place.
+ *
+ * Reasons should be short and to the point.
+ *
+ * If @window is given, the session manager may point the user to
+ * this window to find out more about why the action is inhibited.
+ *
+ * Returns: A non-zero cookie that is used to uniquely identify this
+ * request. It should be used as an argument to g_application_uninhibit()
+ * in order to remove the request. If the platform does not support
+ * inhibiting or the request failed for some reason, 0 is returned.
