This is example of code from MSDN.
The idea simple (less or more): you perform SmartcardT1Request. It prepares
T=1 block for you. You send it to the device, get the answer, put it back
into the structure and call SmartcardT1Reply.If the return value is
STATUS_MORE_PROCESSING_REQUIRED you should continue since handling of APDU
is not finished yet. Otherwise you are finished (successfully or not).
I don't remember in which fields of SmartcardExtension you have
incoming/outgoing APDU and in which fields you have T=1 block, but I'm sure
there is sample in DDK.

// Run this loop as long as the protocol requires to send data
do {
    // Copy data to SmartcardExtension->SmartcardRequest.Buffer
    // embedded in a T=1 frame
    status = SmartcardT1Request(SmartcardExtension);
    if (status != STATUS_SUCCESS)
        return status;

    // Send T=1 frame to smart card
    status = DriverSendDataToSmartcard(?);
    if (status != STATUS_SUCCESS)
        return status;

// Now set appropiate timeout (This example calculates the time-out in ms)
// Timeout = SmartcardExtension->CardCapabilities.T1.BWT *
// (SmartcardExtension->T1.Wtx ? SmartcardExtension->T1.Wtx : 1);

    // receive T=1 frame from smart card
    status = DriverReceiveDataFromSmartcard(?);
    if (status != STATUS_SUCCESS)
        return status;

    // Check T=1 protocol status and copy any data back to user buffer
    status = SmartcardT1Reply(SmartcardExtension);

} while (status == STATUS_MORE_PROCESSING_REQUIRED);

return status;
