XkbSetDeviceButtonActions(3)					   XKB FUNCTIONS				      XkbSetDeviceButtonActions(3)

NAME
XkbSetDeviceButtonActions - Change only the button actions for an input extension device SYNOPSIS
Bool XkbSetDeviceButtonActions (Display *dpy, XkbDeviceInfoPtr device, unsigned int first_button, unsigned int num_buttons); 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 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 X Version 11 libX11 1.6.0 XkbSetDeviceButtonActions(3)

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 X Version 11 libX11 1.2.1 XkbGetDeviceButtonActions(3)
