Re: [Caml-list] string buffer as (in|out)_channel

["Yaron M. Minsky" <yminsky@cs.cornell.edu>]

I think this is the kind of place where it would make sense to use the
object system.  That is, in addition to the low-level in_channel and
out_channel, which essentially serve as proxies for unix file-descriptor
based channels, there should be I/O objects with a standard signature
for files, strings, buffers, etc.  I actually have done a simple version
of this for myself as part of the SKS project, but I think something
along these lines would be useful as a standard part of ocaml, including
integration with printf and other places in the standard library that
use I/O.  

As for your precise question, I don't myself know of any way to convert
a Buffer.t to an i/o channel.
