XkbSetDeviceButtonActions(3Xkb) 				  XKBLIB FUNCTION				   XkbSetDeviceButtonActions(3Xkb)

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

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

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

       - actions
	      *** MISSING ***

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
