Flags for Fs_functions.openfile

O_CLOEXEC doesn't exist, because this flag is unconditionally added by libuv. O_SHARE_DELETE, O_SHARE_WRITE, O_SHARE_READ are always added on Windows, unless O_EXLOCK is specified.

type file_kind = Uwt_base.Fs_types.file_kind =

| S_REG
(*
Regular file
*)
| S_DIR
(*
Directory
*)
| S_CHR
(*
Character device
*)
| S_BLK
(*
Block device
*)
| S_LNK
(*
Symbolic link
*)
| S_FIFO
(*
Named pipe
*)
| S_SOCK
(*
Socket
*)
| S_UNKNOWN
(*
Everything else - possible on some platforms.
*)

type symlink_mode = Uwt_base.Fs_types.symlink_mode =

| S_Default
| S_Dir

indicates that path points to a directory.
*)
| S_Junction
(*

*)

On Windows it can be specified how to create symlinks.

type access_permission = Uwt_base.Fs_types.access_permission =

| Read
(*
Read permission
*)
| Write
(*
Write permission
*)
