XSeBMap(1) X Version 11 XSeBMap(1)XSetDeviceButtonMapping(3X11) X FUNCTIONS XSetDeviceButtonMapping(3X11)NAME
XSetDeviceButtonMapping, XGetDeviceButtonMapping - query or change
device button mappings
SYNTAX
int XSetDeviceButtonMapping(display, device, map, nmap)
Display *display;
XDevice *device;
unsigned char map[];
int nmap;
int XGetDeviceButtonMapping(display, device, map_return, nmap)
Display *display;
XDevice *device;
unsigned char map_return[];
int nmap;
ARGUMENTS
display Specifies the connection to the X server.
device Specifies the device whose button mapping is to be queried
or changed.
map Specifies the mapping list.
map_return Returns the mapping list.
nmap Specifies the number of items in the mapping list.
DESCRIPTION
The XSetDeviceButtonMapping request sets the mapping of the specified
device. If it succeeds, the X server generates a DeviceMappingNotify
event, and XSetDeviceButtonMapping returns MappingSuccess. Element
map[i] defines the logical button number for the physical button i+1.
The length of the list must be the same as XGetDeviceButtonMapping
would return, or a BadValue error results. A zero element disables a
button, and elements are not restricted in value by the number of phys‐
ical buttons. However, no two elements can have the same nonzero
value, or a BadValue error results. If any of the buttons to be
altered are logically in the down state, XSetDeviceButtonMapping
returns MappingBusy, and the mapping is not changed.
XSetDeviceButtonMapping can generate BadDevice, BadMatch, and BadValue
errors.
The XGetDeviceButtonMapping request returns the current mapping of the
specified device. Buttons are numbered starting from one. XGetDevice‐
ButtonMapping returns the number of physical buttons actually on the
device. The nominal mapping for a device is map[i]=i+1. The nmap
argument specifies the length of the array where the device mapping is
returned, and only the first nmap elements are returned in map_return.
XGetDeviceButtonMapping can generate BadDevice or BadMatch errors.
DIAGNOSTICS
BadDevice An invalid device was specified. The specified device does
not exist or has not been opened by this client via XOpen‐
InputDevice. This error may also occur if the specified
device is the X keyboard or X pointer device.
BadMatch This error may occur if an XGetDeviceButtonMapping or XSet‐
DeviceButtonMapping request was made specifying a device
that has no buttons.
BadValue Some numeric value falls outside the range of values
accepted by the request. Unless a specific range is speci‐
fied for an argument, the full range defined by the argu‐
ment's type is accepted. Any argument defined as a set of
alternatives can generate this error.
