Overview
XkbGetKeyboard allocates and returns a pointer to a keyboard description. It queries the server for those components specified in the which parameter for device device_spec and copies the results to the XkbDescRec it allocated. The remaining fields in the keyboard description are set to NULL. The valid masks for which are those listed in Table 1.

XkbGetKeyboard is used to read the current description for one or more components of a keyboard device. It calls XkbGetKeyboardByName(3) as follows:
XkbGetKeyboardByName(dpy, device_spec, NULL, which, which, False).
If successful, XkbGetKeyboard returns a pointer to a newly allocated XkbDescRec structure, which is described in XkbGetKeyboardByName(3), and which should be freed with XkbFreeKeyboard(3). If XkbGetKeyboard does not succeed, it returns NULL.
