/*! \brief Add a page to a property sheet

    Called by a plugin or the NetIDMgr application to add a page to a
    property sheet.

    Pages can only be added before the property sheet is made visible
    to the user.

    \param[in] sheet The property sheet to add the page to

    \param[in] credtype The credentials type ID of the owner of the
        property page.  This should be set to ::KCDB_CREDTYPE_INVALID
        if the type is not relevant.

    \param[in] ordinal Requested ordinal.  A positive integer which is
        used to order the pages in a property sheet.  The pages are
        ordered based on ordinal first and then alphabetically by
        credentials type name.  If the type is unavailable, then the
        ordering is undefined.  Ordinals for credential type property
        pages can be in the range from 0 to 127.  Ordinals 128 and
        above are reserved.  Passing in 0 will work for credentials
        providers unless they provide more than one property page per
        credential, in which case the ordinal should be used to
        enforce an order.

    \param[in] ppage Pointer to structure that will be passed to
        CreatePropertySheetPage() to create the property page.  The
        structure is not managed by NetIDMgr at all, and must exist
        until the status of the property sheet changes to
        ::KHUI_PS_STATUS_RUNNING.  The same pointer will be found in
        the \a p_page member of the ::khui_property_page structure.

    \param[out] page A pointer will be returned here that will point
        to the newly created khui_property_page structure.  Specify
        NULL if this value is not required.  You can use
        khui_ps_find_page() to retrieve a pointer to the structure
        later.
