static MyStruct *interesting_struct = NULL;

 if (g_once_init_enter_pointer (&interesting_struct))
   {
     MyStruct *setup_value = allocate_my_struct (); // initialization code here

     g_once_init_leave_pointer (&interesting_struct, g_steal_pointer (&setup_value));
   }

 // use interesting_struct here

Parameters

location location of a static initializable variable containing NULL
