RTIXMLExtensionClass

Hi,

How can use the function RTIXMLExtensionClass  in my program. I found some programs seems used older version of the function, so how can I

use it in my program, specifically the 1st and the last arguments!!

struct RTIXMLExtensionClass { 

    /*i @brief Init flag */

    int _init;

    /*i 

      @brief Tag name 

    */

    char * _tagName;

    /*i

      @brief User data

    */

    void * _userData;

    /*i

      @brief Indicates if duplicate objects are allowed

    */

    RTIBool allowDuplicatedObjects;

    /*i

      @brief Indicates if the class is a root class

    */

    RTIBool isRoot;

    /*i 

      @brief Function to call when a start tag is  found within an object of this RTIXMLExtensionClass. 

    */

    RTIXMLExtensionClassOnStartTagFunction onStartTagFcn;

    /*i 

      @brief Function to call when a end tag is found within an object of this RTIXMLExtensionClass.. 

    */

    RTIXMLExtensionClassOnEndTagFunction onEndTagFcn;

    /*i 

      @brief Function to call when the start tag is equal to the tagName. 

    */

    RTIXMLExtensionClassNewObjectFunction newObjectFcn;

    /*i 

      @brief Function to call when we want to delete an object. 

    */

    RTIXMLExtensionClassDeleteObjectFunction deleteObjectFcn;

    /*i 

      @brief Function to call when we want to save an object. 

    */

    RTIXMLExtensionClassSaveObjectFunction saveObjectFcn;

};
