Problem using RECORDFUNCTION

Hi All,

I am trying to mimic the following command line curl request in libcurl programatically in C/C++. Instead of reading data from a file though, I want to send binary data from a buffer in memory:
curl "https://website.net:443/Command?appId=XXX&appKey=YYY5&id=ZZZ" -H "Content-Type: AAA;codec=BBB" -H "Accept-Language: ENUS" -H "Transfer-Encoding: chunked" -H "Accept: application/xml" -H "Accept-Topic: New" -k --data-binary @data.bin -v

I am using post-callback.c as a model. I am have set up the headers correctly. What I dont fully understand is how to use READFUNCTION. When I use the technique in post-callback, I get the following error below. Could you point me to an example of how to use READFUNCTION with binary data from a buffer? I would like to see more examples.

Thanks in advance.
