||
| 22 | <dt><b>oop_glib_new</b> |
||
| 23 | <dd>Create a liboop source which uses the |
||
| 24 | <a href="http://www.gtk.org/rdp/glib/glib-the-main-event-loop.html">GLib |
||
| 25 | Main Event Loop</a> for events. There is only one such event loop (the |
||
| 26 | GMainLoop structure really represents a loop context, not a fully independent |
||
| 27 | event loop), so this function is global. You may call it multiple times; it |
||
| 28 | will return the same event source, but keep count of the number of users.<p> |
||
| 29 | |||
| 30 | Events will be dispatched when the GLib event loop is run, either directly |
||
| 31 | via g_main_run() or indirectly via gtk_main().<p> |
||
| 32 | |||
| 33 | <dt><b>oop_glib_delete</b> |
||
| 34 | <dd>Delete the liboop source created with oop_glib_new(). This decrements the |
||
| 35 | count of users; when oop_glib_delete has been called as many times as |
||
| 36 | oop_glib_new, the event source is removed.<p> |
||
| 37 | |||
| 38 | <dt><b>oop_glib_return</b> |
||
| 39 | <dd>Since the event source is run by GLib, the main program has no direct way |
||
| 40 | of retrieving a value returned by an event handler. Instead, when the loop is |
||
| 41 | terminated, the GLib event loop should return, and the caller can use this |
||
| 42 | function to request the specific termination code.<p> |
||
| 43 | |||
| 44 | This function isn't commonly used. <b>Furthermore, GLib event loop termination |
||
| 45 | does not currently work.</b> In other words, ignore this for now. |
