   Always SOUNDS so simple  :-)

   I always wind up having to write fill-ins for the
   missing/very-different library routines between
   Win and Lin.

   Anyway, I'm not sure about the fascination with RAR.
   It is good, but then so are many others that are more
   modern/portable/supported.

   Found an interesting "loop-based" approach to an Str2Int64()
   today. Basically it does powers of ten on each digit (derived
   from the ASCII values of the digits minus-48). It MAY be a bit
   faster than the one I wrote the other day for Pascal that
   involves 'shrinking down' the presented number. I'll have
   to benchmark. Mine only used integer subtraction and ONE
   modulo. Not AS many steps. But, we'll see.

   I was writing a "disk visualizer" the other day (turned out
   pretty well) but Int64 numbers/functions ARE involved. Today
   I took that to write a 'C' "Disk Blaster" ... kinda like using
   'dd' to zero (or pattern-write) a whole drive but because it's
   not as complex it's about 30% quicker. Added a 'skitter' option
   that's applied AFTER the prescribed number of bytes are
   overwritten ... 'skittering' means writing yer zero/pattern
   block roughly (a little randomness added to annoy) every
   50mb on the REST of the disk area. It is not 'erasure'
   per-se, but kinda 'corrupts' and is 50x as fast. You can
   go thru a 1tb disk in an external USB3.0 fixture in about
   five minutes with 'skittering'. So, you totally obliterate
   the X-bytes you're most paranoid about and then randomly
   insert junk in the rest.

   Just gotta smooth-out the params ... there's no slack
   right now. Something like 'dd' params would be good.
   It always uses the equiv of "bs=1M" ... seems the best
   compromise after some experimentation. My visualizer
   made it easy to see if the blaster util was doing it
   right.

   FYI - I have a PILE of old HDDs ... some just Too Old,
   others Flakey. They NEED to be wiped, or at least
   quasi-wiped, before disposal. If I have the time I
   strip them of the magnets and pretty platters, but
   that takes 20-30 minutes per so sometimes I'll just
   trash the whole thing. (a cold-chisel and big
   hammer will also trash old hdd's really well  :-)
