We may have to revert to using open instead but I'm wondering about the
umask 022 that you referenced.  You will have to assume that I don't
have a clue as to what umask is......

Your umask determines the default permissions of files you create. I think the
creation mode is 0666 & ~mask. So, for example, if you create a file under
umask 022, its mode would be 0666 & ~022 = 0644, meaning owner can read and
write, group can read, and others can read.

You might be wanting umask 077. 0666 & ~077 = 600, meaning that owner can read
and write but nobody else can do anything to the file.

You might just try setting your umask to 077 (that's octal) before doing the
fopen to see if the result is what you wanted.
