Module Iostream.Out

Buffered output stream.

Buffered output stream.

class type t = object ... end

An output stream, ie. a place into which we can write bytes.

val create : ?flush:(unit -> unit) -> ?close:(unit -> unit) -> output_char:(char -> unit) -> output:(bytes -> int -> int -> unit) -> unit -> t

Create a new output stream from raw components.

val dummy : t

Dummy output, drops everything written to it.

val of_buffer : Stdlib.Buffer.t -> t

of_buffer buf is an output channel that writes directly into buf. flush and close have no effect.

val output_char : t -> char -> unit

Output a single char

val output : t -> bytes -> int -> int -> unit

Write the slice of bytes.

val close : t -> unit

Close the stream. Idempotent.

val flush : t -> unit

Ensure the bytes written so far are indeed written to the underlying storage/network socket/… and are not just sitting in a buffer.

val output_string : t -> string -> unit

Output the whole string.

val output_line : t -> string -> unit

Output the whole string followed by '\n'.

val output_lines : t -> string Stdlib.Seq.t -> unit

Output a series of lines, each terminated by '\n'.

val output_int : t -> int -> unit

Output an integer in decimal notation.

val tee : t list -> t

tee ocs is an output that accepts bytes and writes them to every output in ocs. When closed, it closes all elements of oc.

val of_unix_fd : ?close_noerr:bool -> ?buf:bytes -> Unix.file_descr -> t
