Module `Core__Core_unix.IOVec`

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.

val of_string : ?⁠pos:int -> ?⁠len:int -> string -> string t

of_string ?pos ?len str

returns: an I/O-vector designated by position pos and length len in string str.

raises Invalid_argument: if designated substring out of bounds.

parameter pos: default = 0

parameter len: default = String.length str - pos

val of_bigstring : ?⁠pos:int -> ?⁠len:int -> bigstring -> bigstring t

of_bigstring ?pos ?len bstr

returns: an I/O-vector designated by position pos and length len in bigstring bstr.

raises Invalid_argument: if designated substring out of bounds.

parameter pos: default = 0

parameter len: default = String.length str - pos

val drop : 'buf t -> int -> 'buf t

drop iovec n drops n characters from iovec.

returns: resulting I/O-vector.

raises Failure: if n is greater than length of iovec.
