(** This module manages file upload parameters. *)

type upload_manager
  (** Manages the file upload parameters of a certain request *)

val get : upload_manager -> string -> Netcgi.cgi_argument
    (** Returns the CGI argument containing the file upload information for
     * the file upload box with the passed name. This name is what is
     * specified in the "name" attribute of ui:file.
     * 
     * See netcgi.mli for accessor functions for [cgi_argument] values.
     * 
     * This function raises [Not_found] if there is no ui:file box with
     * the passed name. This function returns a pseudo argument with
     * empty value, empty filename, and empty MIME type if the browser did
     * not send the corresponding CGI argument to the server. (Note:
     * At least Netscape browsers always send CGI arguments even if the
     * user did not specify files to upload, and these arguments
     * have empty value, empty filename, and empty MIME type. It is a
     * good idea to check for an empty filename in order to find out
     * whether the upload box was used or not.)

val init : Wd_types.environment -> Wd_types.interactors -> upload_manager
    (** Scans the available CGI parameters for file uploads, and initializes
     * this module.
     * - It is required that the CGI module is already initialized
     * (in [environment])
     * - The argument of this function is the interactor definition of the
     * page that has been submitted.
