In the recently received Tech Note 246, "Mixing HFS and C File I/O"
(thanks to Roger L. Long at the Wolfskill & Dowling residence and
comp.binaries.mac), it says not to mix C calls like fopen() with HFS
calls.  However, is it permissible to mix low level C calls like open()
with HFS calls?  The MPW 3.0 C manual says it's acceptable as long as you
don't close or modify the file pointer by using the reference number.  And
in fact the FIOREFNUM command to ioctl gives the Mac's vrefnum for the
file (see page 126).
