DMXAddScreen(3)       DragonFly Library Functions Manual       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 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.
