Hi, Daniel,

This is what I read:

[quote]
From http://curl.haxx.se/libcurl/c/libcurl-tutorial.html, part "Uploading
data to a Remote Site".

"
The read callback should have a prototype similar to:

 size_t function(char *bufptr, size_t size, size_t nitems, void *userp);

Where bufptr is the pointer to a buffer we fill in with data to upload
and size*nitems is the size of the buffer and therefore also the
maximum amount of data we can return to libcurl in this call. The
'userp' pointer is the custom pointer we set to point to a struct of
ours to pass private data between the application and the callback.

 curl_easy_setopt(easyhandle, CURLOPT_READFUNCTION, read_function);

curl_easy_setopt(easyhandle, CURLOPT_READDATA, &filedata);

Tell libcurl that we want to upload:

 curl_easy_setopt(easyhandle, CURLOPT_UPLOAD, 1L);

And here is what I'd like to see:

At least this way it will be consistent with the
http://curl.haxx.se/libcurl/c/libcurl-tutorial.html part "Handle the
Easy libcurl", where it
talks about write function.

And thank you for the FAQ pointer. I was linking against wrong lib.

Thank you.
