Module Core_unix.Native_file
This sub-module provides the normal OCaml Unix functions that deal with file size using native ints. These are here because, in general, you should be using 64bit file operations so that large files aren't an issue. If you have a real need to use potentially 31bit file operations (and you should be dubious of such a need) you can open this module
type stats

{
st_dev : int;

st_uid : int;
User id of the owner
st_gid : int;
Group ID of the file's group
st_rdev : int;
Device minor number
st_size : int;
Size in bytes

}
The informations returned by the
UnixLabels
.stat calls.
val sexp_of_stats : stats -> Ppx_sexp_conv_lib.Sexp.t
val stats_of_sexp : Ppx_sexp_conv_lib.Sexp.t -> stats
val stat : string -> stats
Return the information for the named file.
val lstat : string -> stats
Same as
UnixLabels
.stat, but in case the file is a symbolic link, return the information for the link itself.
val fstat : File_descr.t -> stats
Return the information for the file associated with the given descriptor.
val lseek : File_descr.t -> int -> mode:seek_command -> int
val truncate : string -> len:int -> unit
val ftruncate : File_descr.t -> len:int -> unit
