This interface is used to obtain all other supported interfaces. It is the structure that is given to you as a pointer in the request i_reqHandle parameter in the IProcessRequest Function. All functions require you to give them the original handle you received in IProcessRequest.
This interface also retrieves information about the type of request that is being processed. Knowing the type of request is useful in deciding how to apply a record selection formula to a report that is being scheduled and/or viewed. See SetSelectionFormula Function.
