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.
