# Class type Csv.out_obj_channel

    class type out_obj_channel = object .. end

The most basic output object for best interoperability.

    method output : Bytes.t -> int -> int -> int

`output s ofs len` writes up to `len` bytes of the substring `s.[ofs .. ofs+len-1]`. Return the number of bytes actually written. When the channel is non-blocking, and there are currently no bytes to write, the number 0 must be returned.

    method close_out : unit -> unit

Flushes the buffer, if any, and closes the channel for output.
