# Class type Csv.in_obj_channel

    class type in_obj_channel = object .. end

The most basic input object for best interoperability.

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

`input buf ofs len` reads up to `len` octets from the channel and puts them in the substring `buf.[ofs .. ofs+len-1]`. Returns the number of octets actually read (and stored). When the channel is non-blocking, and there are currently no bytes to read, the number 0 will be returned.
Raises `End_of_file` when there are no more bytes to read.

    method close_in : unit -> unit

Closes the channel for input.
