This is an on-the-fly mod of a subroutine I keep around for getting
info about sun screens:

#include <sun/fbio.h>
#include <sys/file.h>
#include <sys/ioctl.h>
#include <stdio.h>

#define AND  &&
#define OR   ||
#define NOT  !

  /* Get some info about a screen device

                         Ref:  1.  pp. 119-129, SunCore Ref Manual
                               2.  man entry for "fbio(4S)"
			       3.  /usr/include/sun/fbio.h  */

screen_info (screen_name, type, height, width, depth, cmsize, size)
	char *screen_name;
	int *type, *width, *height, *depth, *cmsize, *size;
{
	int screen_fd;
	int stat;
	struct fbtype fb;

  screen_fd = open (screen_name, O_RDWR, 0);
  if (screen_fd < 0)
    {
      perror ("screen_info:  Open on framebuffer failed");
      return 0;
    }
  stat = ioctl (screen_fd, FBIOGTYPE, &fb);
  if (stat < 0)
    {
      perror ("screen_info:  ioctl on framebuffer failed");
      close (screen_fd);
      return 0;
    }
  close (screen_fd);

  *type = fb.fb_type;
  *width = fb.fb_width;
  *height = fb.fb_height;
  *depth = fb.fb_depth;
  *cmsize = fb.fb_cmsize;		/* colormap size */
  *size = fb.fb_size;			/* ?? */

  return 1;
}
