Even if that works, you are supposed to use an asynchronous mechanism
like you used in the unmount case. For some volumes actually snychronous
calls may be used, but you can not rely on that.

Everything is OK with this unmount helper, except that you need a main
loop:


GMainLoop *main_loop;
main_loop = g_main_loop_new (NULL, TRUE);

g_main_loop_run (main_loop);

the main loop should be run right before the return call.

Note that your application will not exit unless you quit the main loop,
using g_main_loop_quit() [for instance in your callback].

best regards,
