NAME
XkbGetDeviceButtonActions - Query the button actions associated with an X Input Extension device
SYNOPSIS
Status XkbGetDeviceButtonActions (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, XkbGetDeviceButtonActions 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
