Re: Get data from pipe

Hello,

However when I ask for the entire document, because it's a binary stream, there is no cr/lf, or - better - there can be any somewhere or none and it's difficult to know the exact amount of data returned.

So, in pseudo-code, you'd do something like this:

   a) Create/open a new IFS file with the open() API.

   b) Create the pipes with the pipe() API.

   c) Spawn a new job (mapping the pipes to stdin/stdout/stderr)
        for your "C API" to run under.

   d) Use the read() API to read a chunk of data from the pipe.
        (reading from the FD for the pipe.)

          len = read(pipe: %addr(buf): %size(buf));

   e) If len > 0, write the data to the IFS File.  Be sure to use
      the length returned by read() to avoid extra garbage chars.

          callp write(stmf: %addr(buf): len);

   f) if len > 0, go back to step (d).  Keep doing this until
      len <= 0, that's when you've reached the end of the data
      on the pipe.

   g) Close the IFS file and the pipes.

Does that make sense?
