  .SH NAME
  DMXGetInputAttributes \- determine input device attributes
  .SH SYNOPSIS
  .B #include <X11/extensions/dmxext.h>
  .sp
  .nf
  .BI "Bool DMXGetInputAttributes(Display " *dpy ,
  .BI "                           int " id ,
  .BI "                           DMXInputAttributes " *attr );
  .fi
  .SH DESCRIPTION
  .B DMXGetInputAttributes()
  returns information about the input device specified with
  .IR id .
  This information cannot be
  obtained from the
  .BR XListInputDeivices (__libmansuffix__)
  call.
  .I id
  is the same as that used by the
  .BR XListInputDevices (__libmansuffix__)
  call, and must be in
  the range 0 to one less than the value returned by
  .BR DMXGetInputCount(__libmansuffix__) ,
  inclusive.
  .PP
  The
  .B DMXInputAttributes
  structure is:
  .sp
  .nf
  typedef struct {
      DMXInputEnum inputType;
      int          physicalScreen;
      int          physicalId;
      Bool         isCore;
      Bool         sendsCore;
      const char   *name;
      Bool         detached;
  } DMXInputAttributes;
  .fi
  .PP
  The value of
  .I inputType
  will always be valid, and will have one of the following values,
  depending on the type of input:
  .B DMXLocalInputType ", " DMXConsoleInputType ", or" DMXBackendInputType .
  .PP
  For local devices, all other fields returned, except
  .I isCore " and " sendsCore ,
  are invalid.
  .PP
  For console devices, 
  .I physicalScreen " and " physicalID
  will be invalid, and
  .I name
  will return the name of the X server on which the console window is
  displayed.
  .PP
  For back-end devices,
  .I physicalScreen
  will identify the back-end display and can be used as an argument to
  .BR DMXGetScreenAttributes (__libmansuffix__)
  to obtain more information;
  .I physicalId
  will be the XInput device id on the back-end X server; and
  .I name
  will be invalid (since it does not provide any additional information
  that cannot be obtained with
  .BR DMXGetScreenAttributes (__libmansuffix__)).
  .PP
  If
  .I isCore
  is
  .BR True ,
  then this device is active as a true core input device and will send
  core events.  If
  .B sendsCore
  is True, then this device is an XInput extension device, but sends core
  events
  .I instead
  of extension events.  This behavior is different from that of XFree86 or
  Xorg, where XInput extension devices may send
  .I both
  extension events and core events.
  .PP
  If
  .I detached
  is True, then this device has been detached and is no longer producing
  input events.  The device may be reattached using
  .BR DMXAddInput (__libmansuffix__).
  .SH "RETURN VALUE"
  .B DMXGetInputAttributes()
  returns
  .B True
  unless there is a protocol error.
  .PP
  .B DMXGetInputAttributes()
  can generate
  .B BadValue
  (if the value of
  .I id
  is out of range).
