There is also currently no undeprecated Carbon API for creating a

Until then, we recommend using either the deprecated Quickdraw API, or
NSCursor.
Thanks for the suggestions.
As far as I can tell, NSCursor is Cocoa, so no good for my C only code,
and I tried QD, but it doesn't really work. Yes the cursor initially
disappears (from the whole screen, which is not what I want), but if
the user then clicks the mouse, it comes back again. Given this,
I'm not sure if there's any point in trying to implement the trickier
business of tracking the cursor, and changing it when it's over
my window using QD. It's into diminishing returns for me at this point.
There are enough headaches in trying to figure out how to use
IOI2CSendRequest to keep me busy. A higher level interface for controlling
the monitor settings would be a good thing too, but I shouldn't complain
too much, at least there is an interface (unlike win32!), and at least
it's associated with the display (unlike Linux!).
I do hope the new Carbon API is a little smarter, and allows setting
cursors as a window attribute ...
