NAME
XkbGetDeviceButtonActions - Query the button actions associated with an X Input Extension device

SYNOPSIS
Status XkbGetDeviceButtonActions ( dpy, device_info, all_buttons, first_button, num_buttons )
      Display * dpy;
      XkbDeviceInfoPtr device_info;
      Bool all_buttons;
      unsigned int first_button;
      unsigned int num_buttons;

ARGUMENTS

- 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

DESCRIPTION

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.
