Daniel,
Thanks for the pointer to this sample program. I have one question about setting the CURLOPT_POSTFIELDSIZE_LARGE option, which I think is preferable if I am posting the contents of a large file. Should the parameter curl_easy_setopt() be the size of the data transferred with each call to the read_callback function, or the total size? If I am reading in the content from a file, maybe this should be the size of the file.

I am not sure what effect setting the CURLOPT_POSTFIELDSIZE_LARGE really has. I have read the documentation, but it is not clear. Does this set the maximum number of bytes to transfer?
Thanks,
Tim.
