NAME

       Char - Character operations.

Module
       Module   Char

Documentation
       Module Char
        : sig end

       Character operations.

       val code : char -> int

       Return the ASCII code of the argument.

       val chr : int -> char

       Return the character with the given ASCII code.  Raise Invalid_argument Char.chr if the argument is outside the range 0--255.

       val escaped : char -> string

       Return a string representing the given character, with special characters escaped following the lexical conventions of Objective Caml.

       val lowercase : char -> char

       Convert the given character to its equivalent lowercase character.

       val uppercase : char -> char

       Convert the given character to its equivalent uppercase character.

       type t = char

       An alias for the type of characters.

       val compare : t -> t -> int

       The  comparison function for characters, with the same specification as Pervasives.compare .  Along with the type t , this function compare
       allows the module Char to be passed as argument to the functors Set.Make and Map.Make .

NAME

       Digest - MD5 message digest.

Module
       Module	Digest

Documentation
       Module Digest
	: sig end

       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.

       Since 4.00.0
