NAME

       XkbSetDeviceButtonActions - Change only the button actions for an input extension device

SYNOPSIS

       Bool  XkbSetDeviceButtonActions  (Display  *dpy,  XkbDeviceInfoPtr  device,  unsigned  int
              first_button, unsigned int num_buttons);

ARGUMENTS

       - dpy  connection to X server

       - device
              structure defining the device and modifications

       - first_button
              number of first button to update, 0 relative

       - num_buttons
              number of buttons to update

DESCRIPTION

       XkbSetDeviceButtonActions assigns actions to  the  buttons  of  the  device  specified  in
       device_info->device_spec.   Actions  are  assigned  to  num_buttons buttons beginning with
       first_button and are taken from the actions specified in device_info->btn_acts.

       If the server does not support assignment of Xkb  actions  to  extension  device  buttons,
       XkbSetDeviceButtonActions has no effect and returns False. If the device has no buttons or
       if first_button or num_buttons specify buttons outside of the valid range as determined by
       device_info->num_btns,   the   function  has  no  effect  and  returns  False.  Otherwise,
       XkbSetDeviceButtonActions sends a request to the server to  change  the  actions  for  the
       specified buttons and returns True.

       If  the  actual  request  sent  to  the server involved illegal button numbers, a BadValue
       protocol  error  is  generated.  If  an  invalid  device  identifier   is   specified   in
       device_info->device_spec,  a  BadKeyboard  protocol  error  results.  If the actual device
       specified in device_info->device_spec does not contain buttons  and  a  request  affecting
       buttons is made, a BadMatch protocol error is generated.

DIAGNOSTICS

       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
