Re: Supercharge your peek_string()

Al,
I've incorporated your peek_string idea into win32lib. Thanks for the idea.

It works fast because I suspect it's written in optimized assembler.

I have no idea what Matt is on about. These strings are just byte arrays
that are terminated with a #00 byte.

Just try this experiment...

  atom addr
  integer len1, len2

  addr = allocate(100)

  poke(addr, "abcdefghijklmnopqrstuvwxyz" & 0)

  len1 = c_func(xlstrlen, {addr})
  len2 = c_func(xlstrlen, {addr + 1})

  -- len2 --> 25
  -- len1 --> 26
