caml_unix_file_descr_of_os, caml_unix_file_descr_of_fd and caml_unix_fd_of_file_descr allow C code to interoperate portably with the Unix library's file_descr values.
Allows printing/logging of Unix.file_descr values without providing full introspection from OCaml-code (for which the C API should be used).
Unix.fdopen allows a program to open additional file streams beyond the standard 0, 1, and 2 already exposed in stdin, stdout and stderr.
