Module Name:

    cannedsd.hxx

Abstract:

    This module contains declarations for the CANNED_SECURITY
    class, which is a repository for the canned Security Descriptors
    used by the utilities.

    Initializing an object of this type generates the canned
    security descriptors used by the utilities, which can
    then be gotten from the object.

    These security descriptors are all in the self-relative
    format.

// The IFS utilities use the following kinds of canned Security Descriptors:

//  ReadOnly    --  System and Admins can read the file.

//  Edit        --  System and Admins can read and write the file,
//                  and can also change its permissions.
//  EditWorld   --  Edit plus NoAcl
