C RFCSDK - How do i receive IDOCs?

Question

Hello everyone.
I am currently programming against the SAP RFCSDK. I have code that makes my C program act as a RFC Server. Basically, what I'm doing is,
char functionName[30];
handle = RfcAccept(argv);
while (true)
  RfcGetName(handle, (char*)functionName);
  //depending on which function was called, call the
  //corresponding handler, which will make calls to
  //RfcGetData() and RfcSendData();
Now, when I began programming this, I was under the impression that the same code could be used for receiving an IDOC. However, I find this is not so. My SAP Consultant has configured my system, such that when I go to BD10, I can send an IDOC to a destination. I tried using the code above, but I see that, when an IDOC is sent, The RfcGetName() function call (which usually blocks until a function is called) returns, but the "functionName" char[30] is NULL.
I was hoping someone here could help me as to which function in the C RFCSDK do I need to use to receive any IDOC from SAP, provided it is sent to a particular destination which my C client has registered with.
Thanks a lot for taking the time to answer my question.

Typically, once you have setup your machine to recieve a fax, you should be able to recieve it.
