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 DMXChangeScreensAttributes(3)
       and DMXGetScreenAttributes(3) functions.

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 visuals, 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(3) API, this function uses screen for both input and output.
