Adam's right. Anyone can look at the source code for FileOpen and see that it
fails to set the result to NULL if an error occurs after the initial FileHand is
allocated. So, the documentation is wrong.

Check err before proceeding. In my apps I wrapped FileOpen with my own function
which
returns NULL if there is an error.
