Module Tar_gz.MakeSource
Parameters
module Writer : Tar.WRITER with type 'a t = 'a Async.tSignature
Returns the next header block or fails with Tar.Header.End_of_stream if two consecutive zero-filled blocks are discovered. Assumes stream is positioned at the possible start of a header block.
really_read fd buf fills buf with data from fd or raises Stdlib.End_of_file.

A simple usage to write a file:
let stream_of_fd fd =
let buf = Bytes.create 0x1000 in
fun () -> match Unix.read fd buf 0 (Bytes.length buf) with
| 0 -> None
| len -> Some (Bytes.sub_string buf 0 len)
| exception End_of_file -> None
let add_file oc filename =
let fd = Unix.openfile filename Unix.[ O_RDONLY ] 0o644 in
let hdr = Tar.Header.make ... in
write_block hdr oc (stream_of_fd fd) ;
Unix.close fdwrite_end oc writes a stream terminator to oc.
