UNCONFIRMED errors and comments from readers:


{85}  line 90;
XCreateBitmapFromData takes argument icon_bitmap_bits which is
const char *. Need to coerce with (const char *).


{94}  Definition of XSetWindowAttributes structure;
I have the July 1993 printing.

The member of the XSetWindowAttributes structure defined as

unsigned long backing_bitplanes;

should be

unsigned long backing_planes;



{595}  In the program code, the function definition for 
XDrawPoint is not valid C syntax as in ANSI C. You cannot 
return a function (as opposed to function pointer)from a 
function. Also, the calls to LockDisplay and FlushGC within
the function have the same superfluous set of round brackets.
If you don't believe me try compiling the code and watch every
ANSI compiler you try it on choke.
