Module Core_unix.Open_flags

module Open_flags: sig .. end

type t

Open_flags.t represents the flags associated with a file descriptor in the open-file-descriptor table. It deals with the same thing as OCaml's open_flag type; however, it uses Core's Flags approach and the underlying integer bitmask representation, and so interoperates more smoothly with C.

include Flags.S

val rdonly : t

access mode.

These three flags are not individual bits like flags usually are. The access mode is represented by the lower two bits of the Open_flags.t. A particular Open_flags.t should include exactly one access mode. Combining different Open_flags.t's using flags operations (e.g +) is only sensible if they have the same access mode.

val wronly : t

val rdwr : t

val creat : t

creation

val excl : t

val noctty : t

val trunc : t

val append : t

val nonblock : t

val dsync : t

val sync : t

val rsync : t

val can_read : t -> bool

can_read t iff t has rdonly or rdwr

val can_write : t -> bool

can_read t iff t has wronly or rdwr

val sexp_of_t : t -> Sexplib.Sexp.t

access mode.
