.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 DMXChangeScreenAttributes (__libmansuffix__)
|
|
and
|
|
.BR DMXGetScreenAttribues (__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.
