NAME

       ata_id_c_string - Convert IDENTIFY DEVICE page into C string

SYNOPSIS

       void ata_id_c_string(const u16 * id, unsigned char * s, unsigned int ofs, unsigned int len);

ARGUMENTS

       id
	   IDENTIFY DEVICE results we will examine

       s
	   string into which data is output

       ofs
	   offset into identify device page

       len
	   length of string to return. must be an odd number.

DESCRIPTION

       This function is identical to ata_id_string except that it trims trailing spaces and terminates the resulting string with null.	len must
       be actual maximum length (even number) + 1.

LOCKING

       caller.

       MD5 message digest.

       This  module provides functions to compute 128-bit ``digests'' of arbitrary-length strings or files. The digests are of cryptographic qual-
       ity: it is very hard, given a digest, to forge a string having that digest. The algorithm used is MD5. This module should not be  used  for
       secure and sensitive cryptographic applications. For these kind of applications more recent and stronger cryptographic primitives should be
       used instead.

       type t = string

       The type of digests: 16-character strings.

       val compare : t -> t -> int

       The comparison function for 16-character digest, with the same specification as	Pervasives.compare  and  the  implementation  shared  with
       String.compare  .  Along with the type t , this function compare allows the module Digest to be passed as argument to the functors Set.Make
       and Map.Make .

       Since 4.00.0

       val string : string -> t

       Return the digest of the given string.

       val substring : string -> int -> int -> t

       Digest.substring s ofs len returns the digest of the substring of s starting at character number ofs and containing len characters.

       val channel : Pervasives.in_channel -> int -> t

       If len is nonnegative, Digest.channel ic len reads len characters from channel ic and  returns  their  digest,  or  raises  End_of_file	if
       end-of-file  is	reached  before  len  characters  are  read.  If len is negative, Digest.channel ic len reads all characters from ic until
       end-of-file is reached and return their digest.

       val file : string -> t

       Return the digest of the file whose name is given.

       val output : Pervasives.out_channel -> t -> unit

       Write a digest on the given output channel.

       val input : Pervasives.in_channel -> t

       Read a digest from the given input channel.

       val to_hex : t -> string

       Return the printable hexadecimal representation of the given digest.

       val from_hex : string -> t

       Convert a hexadecimal representation back into the corresponding digest.  Raise Invalid_argument if the argument is not exactly 32 hexadec-
       imal characters.
