XSetDeviceButtonMapping, XGetDeviceButtonMapping - query or change device button mappings


 #include <X11/extensions/XInput.h>
 int XSetDeviceButtonMapping( Display *display,
                              XDevice *device,
                              unsigned char map[],
                              int nmap);
 int XGetDeviceButtonMapping( Display *display,
                              XDevice *device,
                              unsigned char map_return[],
                              int nmap);
        Specifies the connection to the X server.
        Specifies the device whose button mapping is to be
        queried or changed.
        Specifies the mapping list.
        Returns the mapping list.
        Specifies the number of items in the mapping list.


 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 physical
 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.XGetDeviceButtonMapping 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


        An invalid device was specified. The specified device
        does not exist or has not been opened by this client via
        XOpenInputDevice. This error may also occur if the
        specified device is the X keyboard or X pointer device.
        This error may occur if an XGetDeviceButtonMapping or
        XSetDeviceButtonMapping request was made specifying a
        device that has no buttons.
        Some numeric value falls outside the range of values
        accepted by the request. Unless a specific range is
        specified for an argument, the full range defined by the
        argument's type is accepted. Any argument defined as a
        set of alternatives can generate this error.
