Utility functions for operating over whole tar archives.
val with_next_file : IO.in_channel -> (IO.in_channel -> Header.t -> 'a) -> 'a
Read the next header, apply the function 'f' to the fd and the header. The function should leave the fd positioned immediately after the datablock. Finally the function skips past the zero padding to the next header.
val list : ?level:Header.compatibility -> IO.in_channel -> Header.t list
List the contents of a tar.
val extract_gen : (Header.t -> IO.out_channel) -> IO.in_channel -> unit
extract_gen dest
extract the contents of a tar. Apply dest
on each header to get a handle to the file to write to.
val create_gen :
?level:Header.compatibility ->
(Header.t * (IO.out_channel -> unit)) Stdlib.Stream.t ->
IO.out_channel ->
unit
Create a tar on file descriptor fd from the stream of headers.
val copy_n : IO.in_channel -> IO.out_channel -> int64 -> unit
copy_n ifd odf n
copies exactly n
bytes from ifd
to ofd
.
val skip : IO.in_channel -> int -> unit
skip fd n
reads and throws away n
bytes from fd
.
