I've also been having trouble with the skip command on large files. For
example, I'm testing out the ftp restarting code, so I can download a 33
meg file, and if the connection is dropped after 10 megs have been
downloaded, I can just continue on with the remaining 23 megs. But, I
have a couple of problems...
Firstly, using 'write/append/direct/binary %file.bin large-buffer', if
the large-buffer is 1 meg in size (for example), each time I call
write/append, Rebol allocates 1 more meg of memory, which is very
annoying. I could put a 'recycle' after calling write, but I figured I
could just use open and skip.
So I try -
>> foo: open/binary/direct/write %file.bin
>> foo: skip foo foo/size
...
which should set the file position to the tail, but it crashes. If I
use 'foo: open/direct/write %file.bin' instead, it doesn't crash, but
the file position is only moved a small distance, like 10000 bytes. So
then if I try and write some data, thinking that I'm appending to the
file, I'm just writing over the existing data. There's definitly some
wierd voodoo magic going on :)
