XkbGetDeviceButtonActions(3)     XKB FUNCTIONS    XkbGetDeviceButtonActions(3)

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

       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;

       - 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, XkbGetDeviceButtonAc-
       tions 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, XkbGetDeviceButtonAc-
       tions 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  but-
       tons,  a  BadMatch  status is returned. If first_button and num_buttons
       specify illegal buttons, a BadValue status is returned.

       BadAccess      The Xkb extension has not been properly initialized

       BadAlloc       Unable to allocate storage

       BadKeyboard    The device specified was  not  a  valid  core  or  input
                      extension device

       BadMatch       A  compatible  version  of  Xkb was not available in the
                      server or an argument has correct type and range, but is
                      otherwise invalid

       BadValue       An argument is out of range
