I/O-vectors for scatter/gather-operations

type 'buf t = private {
   buf :'buf; (*Buffer holding the I/O-vector*)
   pos :int; (*Position of I/O-vector in buffer*)
   len :int; (*Length of I/O-vector in buffer*)
}
Representation of I/O-vectors. NOTE: DO NOT CHANGE THE MEMORY LAYOUT OF THIS TYPE!!! All C-functions in our bindings that handle I/O-vectors depend on it.
type 'buf kind 
Kind of I/O-vector buffers
type bigstring = (char, Bigarray.int8_unsigned_elt, Bigarray.c_layout) Bigarray.Array1.t 
val string_kind : string kind
val bigstring_kind : bigstring kind
val empty : 'buf kind -> 'buf t
empty the empty I/O-vector.
val of_string : ?pos:int -> ?len:int -> string -> string t
of_string ?pos ?len str
Raises Invalid_argument if designated substring out of bounds.
Returns an I/O-vector designated by position pos and length len in string str.
pos : default = 0
len : default = String.length str - pos
val of_bigstring : ?pos:int ->
?len:int ->
bigstring -> bigstring t
of_bigstring ?pos ?len bstr
Raises Invalid_argument if designated substring out of bounds.
Returns an I/O-vector designated by position pos and length len in bigstring bstr.
pos : default = 0
len : default = String.length str - pos
val drop : 'buf t -> int -> 'buf t
drop iovec n drops n characters from iovec.
Raises Failure if n is greater than length of iovec.
Returns resulting I/O-vector.

val t_of_sexp : (Sexplib.Sexp.t -> 'buf) -> Sexplib.Sexp.t -> 'buf t
val sexp_of_t : ('buf -> Sexplib.Sexp.t) -> 'buf t -> Sexplib.Sexp.t

Kind of I/O-vector buffers

empty the empty I/O-vector.

of_string ?pos ?len str

of_bigstring ?pos ?len bstr

drop iovec n drops n characters from iovec.
