I would propose another way. I studied your implementation in KMyMoney, and as 
I see it the HTTP-transfer can be very easily encapsulated: In your code you 
call a function which sends a HTTP post request.

I think the best would be to define a OfxPartnerContext (see above) which 
includes a callback.

We could let it point initially to a function which sends a request using 
libcurl internally, but the application would have the possibility to do th 
transfer itself.

There are two important reasons: 

1) the two main users are KMyMoney (KDE) and AqBanking.
KMYMoney uses KDE/QT which have nice functions for HTTP requests which 
integrate seemlessly into the KDE framework.

AqBanking uses its own transfer management (mainly because we want to avoid 
GUI freezes without having to deal with multithreading).

So it would be very nice if the callers would keep control over the transfers.

2) the second reason is that the application needs to be in control over where 
the index files etc are to be stored. This could also be stored within the 
OfxPartnerContext.

What I suggest is something along the line of the following:

/** function prototype */
typedef int (*OFX_PARTNER_POST_FN)(OfxPartnerContext *ctx,
  const char *url, const char postBody, const char *fileName);

struct OfxPartnerContext {
  char *folder; /* donwload folder for index file etc */
  OFX_PARTNER_POST_FN postFn;
};


We could even provide a default postFn which calls curl or whatever you like, 
but still the application would have full control over:
- where files are stored
- how they are retrieved from the partner server.


Kind regards
