Here's what I don't understand.
I'm using the perform call: curl_easy_perform(curl_handle), and the url initiates a stream and the app expects a constant stream of data.
How does (or should) the callback handles it? I mean, is it called constantly since there is a constant flow of data? does it make one call to the callback and return? Am I even using the correct functions?

Thanks,
ER

you have to setup a write callback, and use an unsigned char array as a buffer instead of a short int array. then you can be sure you get the buffer filled correctly, by printf()ing the first few bytes. the easy interface works fine.

then after that, dont cast the bytes to a short int :)
