DMXAddScreen(3)

NAME

       DMXAddScreen - attach a new back-end screen

SYNOPSIS

       #include <X11/extensions/dmxext.h>

       Bool DMXAddScreen(Display *dpy,
                         const char *displayName,
                         unsigned int mask,
                         DMXScreenAttributes *attr,
                         int *screen);

DESCRIPTION

       DMXAddScreen()  attaches  a  back-end  screen to the Xdmx(1) server, in
       place of the previously detached back-end server specified by screen.

       displayName is the name of the new back-end display, mask specifies the
       field  in  attr  that  are  active,  and screen returns the new Xdmx(1)
       screen number for the attached screen.

       The information stored in mask  and  attr is identical to that used  by
       the  DMXChangeScreenAttributes(3X)  and DMXGetScreenAttribues(3X) func-
       tions.

RETURN VALUE

       DMXAddScreen()  will  return  True  if  the  screen  was   successfully
       attached,   and  False  otherwise.   False  will  be  returned  if  the
       -addremovescreens command line option was not specified on the  Xdmx(1)
       command  line, the input value of screen is out of range, screen is not
       currently detached, displayName cannot be opened, has unexpected  visu-
       als,  or  has characteristics that do not match the previously detached
       screen.

       DMXAddScreen() can generate BadLength, BadAlloc, and BadValue errors.

NOTES

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

       Unlike  other  functions  in the DMX(3X) API, this function uses screen
       for both input and output.
