.SH DESCRIPTION
.LP
.I XkbGetDeviceButtonActions 
queries the server for the desired button information for the device indicated 
by the 
.I device_spec 
field of 
.I device_info 
and waits for a reply. If successful, 
.I XkbGetDeviceButtonActions 
backfills the button actions 
.I (btn_acts 
field of 
.I device_info) 
for only the requested buttons, updates the 
.I name, type, supported, 
and 
.I unsupported 
fields, and returns Success.

.I all_buttons, first_button 
and 
.I num_buttons 
specify the device buttons for which actions should be returned. Setting
.I all_buttons 
to True requests actions for all device buttons; if 
.I all_buttons 
is False, 
.I first_button 
and 
.I 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, 
.I XkbGetDeviceButtonActions 
returns BadAccess. If allocation errors occur, a BadAlloc status is returned. If 
the specified device 
.I (device_info->device_spec) 
is invalid, a BadKeyboard status is returned. If the device has no buttons, a 
BadMatch status is returned. If 
.I first_button 
and 
.I num_buttons 
specify illegal buttons, a BadValue status is returned.
