You must first attempt to append a '+' to the filename and then call
stat().  If it fails with ENOENT, the file is not a CDF.  If it succeeds
the S_ISDCF() macro will tell whether it is a CDF.

If you call stat("/etc/inittab", &buf), the information returned will
refer to /etc/inittab+/<cnodename> not to the hidden directory, and
S_ISCDF(buf.st_mode) will return zero.

This requires use of lstat() rather than stat().
