Rich Salz has already written a PD version of FTW, and posted it:

Forget my previous message -- I just decided for completeness's sake to
implement the SysV ftw(3) routine, too.  

To repeat, these are public-domain implementations of the SystemV ftw()
routine, the BSD scandir() and alphasort() routines, and documentation for
same.  The FTW manpage could be more readable, but so it goes.

Anyhow, feel free to post these, and incorporate them into your existing
packages.  I have readdir() routiens for MSDOS and the Amiga if anyone
wants them, and should have them for VMS by the end of January; let me
know if you want copies.

Yours in filesystems,

Anyhow, feel free to post
