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.

XkbGetDeviceButtonActions(3) XKB FUNCTIONS XkbGetDeviceButtonActions(3)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
