- dpy connection to X server
- device_info structure to update with results
- all_buttons True => get information for all buttons
- first_button number of first button for which info is desired
- num_buttons number of buttons for which info is desired
XkbGetDeviceButtonActions queries the server for the desired button information for the device indicated by the device_spec field of device_info and waits for a reply. If successful, XkbGetDeviceButtonActions backfills the button actions (btn_acts field of device_info) for only the requested buttons, updates the name, type, supported, and unsupported fields, and returns Success. all_buttons, first_button and num_buttons specify the device buttons for which actions should be returned. Setting all_buttons to True requests actions for all device buttons; if all_buttons is False, first_button and num_buttons specify a range of buttons for which actions are requested. If a compatible version of Xkb is not available in the server or the Xkb extension has not been properly initialized, XkbGetDeviceButtonActions returns BadAccess. If allocation errors occur, a BadAlloc status is returned. If the specified device (device_info->device_spec) is invalid, a BadKeyboard status is returned. If the device has no buttons, a BadMatch status is returned. If first_button and num_buttons specify illegal buttons, a BadValue status is returned.
15 BadAccess The Xkb extension has not been properly initialized
15 BadAlloc Unable to allocate storage
15 BadKeyboard The device specified was not a valid core or input extension device
15 BadMatch A compatible version of Xkb was not available in the server or an argument has correct type and range, but is otherwise invalid
15 BadValue An argument is out of range
