This time my question is a little easier.  Simply stated, XMatchVisualInfo
and XGetVisualInfo both give me a segmentation fault when I call them.

I have tried allocating space for visualinfo and not allocating, makes
no difference.  Here's a short listing of applicable code:

	display=XOpenDisplay(NULL);
	if (display == NULL)
		quiterr("can`t open display; DISPLAY variable set?");
	screen = DefaultScreen(display);
	screenp = DefaultScreenOfDisplay(display);
	depth = DisplayPlanes(display,screen);
	gc= DefaultGC(display,screen);

	/* We need a visual class with changeable color maps. */

	stat=XMatchVisualInfo(display,screen,depth,PseudoColor,visinfo);
	if(stat==0){
		fprintf(stderr,"cannot get Pseudocolor class visual!\n");
		exit(0);
	}
	visual=visinfo->visual;
	
If there is not an appropriate visual it should just return 0 right?
Any ideas folks?
