Hello.
I want to ask Caml developers about one feature...
Can you officially describe (in the next OCaml package,
for example) the creating of channels with custom
input/output/..etc.. functions? (C or Caml interface -
it doesn't matter)
It is very useful since many OCaml 'standart' functions
work with channels, and I don't want to write my own code
instead of these functions.
Of course, I can dig in the source code and find the
channel definitions, but _documented_ channel-creating
interface will be helpful not only for me.
Bye.

I agree. I just didn't get to it yet but thought it would have been
useful.

If you want your channels to have type in_channel or out_channel, and
be usable with the I/O functions provided by the standard library,
then this is not possible with the current implementation.
However, it is easy to define your own types my_in_channel, my_out_channel
that wrap the system channel types, as well as your own channels, and
provide operations that dispatch on the channel kind, either using
variant types, records of functions, or objects.
