Eo gdb: Implement eo_data_get to get eo data.
Like 79d76fb25ece4ffbf5785b4be2b030f062ef9f2c, this is useful when
debugging a core dump.
It accepts a valid pointer to an object, for example as returned from
$eo_resolve, and a name of a class or mixin, and returns a pointer to
the private data. Essentially the same as efl_data_scope_get(), but also
works on core dumps, and accepts a class name instead of a class
pointer.
Usage:
Print the pointer:
(gdb) print $eo_data_get($eo_resolve(obj), "Efl_Canvas_Object")
$1 = (void *) 0x555555eb9290
Use it directly (e.g. to print a value):
(gdb) print ((Evas_Object_Protected_Data *) $eo_data_get($eo_resolve(obj),
"Efl_Canvas_Object"))->last_event_type
$2 = EVAS_CALLBACK_MOUSE_UP
