Here is a code fragment that determines the depth of a screen:

#include        <suntool/sunview.h>

	...
	Pixrect *screen;
	...
	/* open frame buffer */
	if ((screen = pr_open("/dev/fb")) == 0)
		error("Can't open screen!\n");

	if (screen->pr_depth == 1) {
		/* Black and white screen */
	}
	else if (screen->pr_depth == 8) {
		/* 8 Bit (gray scale or color) */
	}
	else {
		error("Weird monitor depth: %d\n", screen->pr_depth);
	}
	...
