Yes, there should be. There isn't as far as I know (though that
doesn't mean much given my limited experiences in the recesses of
Win32 APIs).
Additionally, even if you did a LBYL instead, you'd open yourself
to a race-condition where the permissions could theoretically
change between the time you check and the time you actually try
to write there. Granted, that's a slim chance and usually would
be a "Doctor, my foot hurts when I do $THIS"/"Well don't do that"
situation where the solution is "don't change the permissions
while running this program".
