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.
