.SH DESCRIPTION

.B DMXAddInput()

is used to attach a new input (or a previously detached input) to the

.BR Xdmx (1)

server.

.I mask

specifies the fields in

.I attr

that are active, and

.I id

returns the device if of the first device in the series that is added.

.PP

The value of

.I mask

is computed from the following values:

.sp

.nf

DMXInputType

DMXInputPhysicalScreen

DMXInputSendsCore

.fi

.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

.I inputType

may have the value

.B DMXConsoleInputType " or " DMXBackendInputType .

.PP

For console devices,

.I name

will specify the display to be used.

.PP

For back-end devices,

.I physicalScreen

will specify the

.BR Xdmx (1)

screen number.

.PP

If

.I sendsCore

is

.BR True ,

the new device will be added as a true core device.

.PP

If a device was removed with

.BR DMXRemoveInput (__libmansuffix__)

an attempt will be made to reconnect the previous devices

.RI ( sendsCore

is ignored in this case).

.PP

.B DMXAddBackendInput()

is a helper function that is used to add input from a back-end server.

With this function,

.I screen

refers to the back-end screen,

.I sendsCore

is

.B True

if the new input should send core events (and it ignored if the input

has been detached), and

.I newId

will hold the device id of the first device in the series added.

.PP

.B DMXAddConsoleInput()

is a helper function that is used to add input from a console.  With

this function,

.I name

is the name of the console display,

.I sendsCore

is

.B True

if the new input should send core events (and it ignored if the input

has been detached), and

.I newId

will hold the device id of the first device in the series added.

.SH "RETURN VALUE"

.B DMXAddInput()

returns

.B True

on success and

.B False

otherwise.

.PP

.B DMXAddInput()

can generate

.B BadValue

(if

.I inputType

is invalid or

.I physicalScreen

is out of range),

.B BadAccess

(if the input has already been attached or if the backend screen is

currently detached).

.SH NOTES

Local devices cannot be attached or detached.

.PP

Attributes that are not specified will default to 0.  This may lead to

unintended results.
