C# Signature:

/// <summary>

    /// The AddAce function adds one or more access control entries (ACEs) to a specified access control list (ACL).
    /// </summary>
    /// <param name="pAcl">A pointer to an ACL. This function adds an ACE to this ACL.</param>
    /// <param name="dwAceRevision">Specifies the revision level of the ACL being modified.</param>
    /// <param name="dwStartingAceIndex">Specifies the position in the ACL's list of ACEs at
    /// which to add new ACEs. A value of zero inserts the ACEs at the beginning of the
    /// list. A value of MAXDWORD appends the ACEs to the end of the list.</param>
    /// <param name="pAceList">A pointer to a list of one or more ACEs to be added
    /// to the specified ACL. The ACEs in the list must be stored contiguously.</param>
    /// <param name="nAceListLength">Specifies the size, in bytes, of the input buffer
    /// pointed to by the pAceList parameter.</param>
    /// <returns>If the function succeeds, the return value is nonzero.</returns>
