.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 XListInputDevices (__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).
