NAME

       DMXGetInputAttributes - determine input device attributes

SYNOPSIS

       #include <X11/extensions/dmxext.h>

       Bool DMXGetInputAttributes(Display *dpy,
                                  int id,
                                  DMXInputAttributes *attr);

DESCRIPTION

       DMXGetInputAttributes()  returns  information about the input device specified with id.  This information
       cannot  be  obtained  from  the  XListInputDevices(3)  call.   id  is  the  same  as  that  used  by  the
       XListInputDevices(3)  call,  and  must  be  in  the  range  0  to  one  less  than  the value returned by
       DMXGetInputCount(3), inclusive.

       The DMXInputAttributes structure is:

       typedef struct {
           DMXInputEnum inputType;
           int          physicalScreen;
           int          physicalId;
           Bool         isCore;
           Bool         sendsCore;
           const char   *name;
           Bool         detached;
       } DMXInputAttributes;

       The value of inputType will always be valid, and will have one of the following values, depending on  the
       type of input: DMXLocalInputType ,  DMXConsoleInputType , or DMXBackendInputType .

       For local devices, all other fields returned, except isCore  and  sendsCore , are invalid.

       For  console  devices,  physicalScreen  and  physicalID will be invalid, and name will return the name of
       the X server on which the console window is displayed.

       For back-end devices, physicalScreen will identify the back-end display and can be used as an argument to
       DMXGetScreenAttributes(3) to obtain more information; physicalId will be the  XInput  device  id  on  the
       back-end  X  server;  and name will be invalid (since it does not provide any additional information that
       cannot be obtained with DMXGetScreenAttributes(3)).

       If isCore is True, then this device is active as a true core input device and will send core events.   If
       sendsCore  is  True,  then  this  device  is an XInput extension device, but sends core events instead of
       extension events.  This behavior is different from that  of  XFree86  or  Xorg,  where  XInput  extension
       devices may send both extension events and core events.

       If  detached  is  True,  then this device has been detached and is no longer producing input events.  The
       device may be reattached using DMXAddInput(3).

RETURN VALUE

       DMXGetInputAttributes() returns True unless there is a protocol error.

       DMXGetInputAttributes() can generate BadValue (if the value of id is out of range).
