What about [CCode (array_length = false)] ulong[] ?
Damn, I really should learn how to read!
XGetKeyboardMapping()'s manpage says:
The X server arbitrarily chooses the keysyms_per_key‐
code_return value to be large enough to report all requested
symbols. A special KeySym value of NoSymbol is used to fill
in unused elements for individual KeyCodes. To free the stor‐
age returned by XGetKeyboardMapping, use XFree.
So the unowned keyword is actually the wrong part. Remove that ...
- public unowned uint[] get_keyboard_mapping (uint first_keycode, int keycode_count, ref int
keysyms_per_keycode_return);
+ public ulong[] get_keyboard_mapping (uchar first_keycode, int keycode_count, ref int
keysyms_per_keycode_return);
... et voilà, no more segfaults when using an array:
$ valac --vapidir=b --pkg=x11 Test.vala && ./Test
On this system sizeof(char) is 1 bytes, sizeof(int) is 4 bytes and sizeof(long) is 8 bytes.
The minimal keycode is 8, the maximal keycode is 255 which makes a total of 248 keycodes.
With this keyboard mapping there are 7 keysyms per keycode, detailed mapping follows:
KeyCode 0 has KeySyms: 0h 0h 0h 0h 0h 0h 0h
[...]
KeyCode 247 has KeySyms: 0h 0h 0h 0h 0h 0h 0h
I've attached updated versions of the patch and the test program.
Best regards
