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.
