Daniel,
thank you so much for your great ideas!
The option --libcurl is pretty cool (even if I did not needed it here)!
Cause: In fact, my read function was simply wrong. It was missing some
bookkeeping, so it returned the same string length always, but never returned
zero to stop.
Solution: For all in the same situation, here is my solution (feel free to copy
it / the trick is to update the offset within the std::string between multiple
invocations of the read function):
class UserData {
public:
const std::string& data;
size_t offset;
UserData(const std::string& data) : data(data), offset(0) {}
};
static size_t onSendRequestChunk(char* const ptr, const size_t size, const
size_t nitems, UserData& userdata) {
const size_t remaining = userdata.data.size() - userdata.offset;
const size_t bytesToSend = min(remaining, size * nitems);
memcpy(ptr, userdata.data.data() + userdata.offset, bytesToSend);
userdata.offset += bytesToSend;
return bytesToSend;
}
Regards
-Markus

If you use the --libcurl flag, you'll probably see that curl.exe sets some
option(s) that your application does not. Like CURLOPT_INFILESIZE.

Do you set the presumed size? If not, do you return zero from the read callback
at the end of data?
