XSetDeviceButtonMapping(3)


NAME

   XSetDeviceButtonMapping, XGetDeviceButtonMapping - query or change
   device button mappings

SYNOPSIS

   #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);

   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 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
       errors.

DIAGNOSTICS

       BadDevice
              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.

       BadMatch
              This error may occur if an XGetDeviceButtonMapping or
              XSetDeviceButtonMapping 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
              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.
