XkbGetDeviceInfoChanges(3)					   XKB FUNCTIONS					XkbGetDeviceInfoChanges(3)

NAME

       XkbGetDeviceInfoChanges	- Query the changes that have occurred in the button actions or indicator names and indicator maps associated with
       an input extension device

SYNOPSIS

       Status XkbGetDeviceInfoChanges (Display *dpy, XkbDeviceInfoPtr device_info, XkbDeviceChangesPtr changes);

ARGUMENTS

       - dpy  connection to X server

       - device_info
	      structure to update with results

       - changes
	      contains notes of changes that have occurred

DESCRIPTION

       The changes->changed field indicates which attributes of the device specified in changes->device have changed.  The  parameters	describing
       the  changes are contained in the other fields of changes. XkbGetDeviceInfoChanges uses that information to call XkbGetDeviceInfo to obtain
       the current status of those attributes that have changed. It then updates the local description of the device in device_info with  the  new
       information.

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, 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 buttons, a BadMatch status is returned. If first_button and num_buttons
       specify illegal buttons, a BadValue status is returned.

DIAGNOSTICS

       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
