RxContext [in]A pointer to the RX_CONTEXT structure for this request.
RxLowIoGetBufferAddress returns a mapped address pointer on success or a NULL on failure.
RxLowIoGetBufferAddress checks that the ParamsFor.ReadWrite.ByteCount member of the LowIoContext member of the RxContext variable is greater than zero and returns a NULL pointer if this is not the case.
RxLowIoGetBufferAddress calls MmGetSystemAddressForMdlSafe to retrieve the mapped address.
