NAME

       ggiOpen, ggiClose - Open and close a visual

SYNOPSIS

       #include <ggi/ggi.h>

       ggi_visual_t ggiOpen(const char *display, ...);

       int ggiClose(ggi_visual_t vis);

DESCRIPTION

       ggiOpen  opens  a visual.  The visual is specified as a display string,
       followed by NULL.  If only  NULL  is  specified,  the  default  display
       target  is  opened,  which  means  first  examining  GGI_DISPLAY,  then
       invoking  display-auto(7).   The  other  arguments  are  for   internal
       purposes  only,  such  as  argptr,  used  to pass driver-specific, non-
       textual information to the driver.

       ggiClose releases and destroys an  open  visual.   This  will  close  X
       windows, return consoles to text-mode, etc.

RETURN VALUE

       ggiOpen  returns the opened visual or NULL for error.  The ggi_visual_t
       is opaque to the  programmer  and  should  only  be  used  through  GGI
       functions.

       ggiClose returns 0 for OK, otherwise a ggi-error(3) code.

EXAMPLES

       Open and closing default visual:

       ggi_visual_t vis = ggiOpen(NULL);

       if(vis==NULL) {
             ggiPanic("Couldn't open default visual!\n");
       }

       /* do stuff */

       ggiClose(vis);

       Open and closing a memory visual:

       ggi_visual_t memvis = ggiOpen("display-memory", NULL);

       if(memvis==NULL) {
             return -1;
       }

       /* do stuff */

       ggiClose(memvis);
