type 'a t
val openfile : ?perm:int -> mode:uv_open_flag list -> string -> file t
  • parameter perm

    defaults are 0o644

val read : ?pos:int -> ?len:int -> file -> buf:bytes -> int t
  • parameter pos

    default is always zero

  • parameter len

    default is always the length of the string / array / Bytes.t

_ba function are unsafe. Bigarrays are passed directly to libuv (no copy to c heap or stack).
