Yeuch! Far cleaner solution is as follows:

#include <suntool/sunview.h>
#include <sunwindow/window_hs.h>
#include <stdio.h>

static Frame	frame;

main()
{
	frame = (Frame) window_create(NULL, FRAME, 0);
	SunViewExit();
}

static
SunViewExit()
{
	int	rootfd = SunViewOpen();

	win_screendestroy(rootfd);
	close(rootfd);
}

static 
SunViewOpen()
{
	int             myfd, rootfd;
	struct screen   rootscreen;

	myfd = (int) window_get(frame, WIN_FD);
	win_screenget(myfd, &rootscreen);
	rootfd = open(rootscreen.scr_rootname, 1);
	return (rootfd);
}

In practice frame would be the base frame of your application.
