Dear all,

Assuming a channel chan has been opened with open_out, is there a
recommended way to write to the underlying file from a C program?

Is it a matter of passing chan to the C program and then extracting the
file descriptor with the help of "caml/io.h" ?

Thanks,

Sébastien.

I would call the channel-writing functions of the OCaml runtime, see
byterun/caml/io.h (and <caml/io.h> for C includes).

Ah, I see, thanks. This would indeed guarantee coherent output, but then
it also means that one has to sprintf to a string before writing to the
channel, right?

Thanks,

Sébastien.
