XSGIDeviceControl(3X11)

     NAME
          XSGIDeviceControl, XSGIDeviceQuery - set/query device
          characteristics for X input devices

     SYNTAX
          #include <X11/extensions/SGIMisc.h>

          Bool XSGIDeviceControl(
            Display *display,
            int device_id,
            char *name,
            char *value
          )

          Bool XSGIDeviceQuery(
            Display *display,
            int device_id,
            char *name,
            char *value
          )

     ARGUMENTS
          display     Specifies the connection to the X server

          device_id   Specifies the id of the device to be accessed

          name        Specifies the name of the device control to be
                      set or queried

          value       Specifies the value to be set for a device
                      control, or the location to store the value for
                      a device query

     DESCRIPTION
          These functions are part of the XSGIMisc extension.
          XSGIMiscQueryExtension(3X11) should be used to determine if
          the extension is supported before calling these functions.

          Device controls represent characteristics of X input devices
          that can be changed.  See input(7) for a description of X
          input devices and common device controls.  Specific devices
          may implement other device controls.

          XSGIDeviceControl returns True if the device control
          specified by name can be set to the specified value.

          XSGIDeviceQuery returns True if name specifies a device
          control or other value that can be queried for the device.
          The array pointed to by value should be large enough to
          contain 24 bytes.

          The device_id used in these calls is the value returned by
          XListInputDevices(3X11).  The device should be opened using
          XOpenDevice(3X11) before calling either of these functions.
