.SH DESCRIPTION

.B DMXAddScreen()

attaches a back-end screen to the

.BR Xdmx (1)

server, in place of the previously detached back-end server specified by

.IR screen .

.PP

.I displayName

is the name of the new back-end display,

.I mask

specifies the field in

.I attr

that are active, and

.I screen

returns the new

.BR Xdmx (1)

screen number for the attached screen.

.PP

The information stored in

.I mask " and " attr

is identical to that used by the

.BR DMXChangeScreensAttributes (__libmansuffix__)

and

.BR DMXGetScreenAttributes (__libmansuffix__)

functions.

.SH "RETURN VALUE"

.B DMXAddScreen()

will return

.B True

if the screen was successfully attached, and

.B False

otherwise.

.B False

will be returned if the

.I \-addremovescreens

command line option was not specified on the

.BR Xdmx (1)

command line, the input value of

.I screen

is out of range,

.I screen

is not currently detached,

.I displayName

cannot be opened, has unexpected visuals, or has characteristics that do

not match the previously detached screen.

.PP

.B DMXAddScreen()

can generate

.BR BadLength ,

.BR BadAlloc ,

and

.B BadValue

errors.

.SH NOTES

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

unintended results.

.PP

Unlike other functions in the

.BR DMX (__libmansuffix__)

API, this function uses

.I screen

for both input and output.
