Yes. You forgot to read the docs properly....
/* the function to invoke as the data recieved */
size_t static write_callback_func(void *buffer, size_t size, size_t
nmemb, void *userp)
{
char **response_ptr = (char**)userp;
/* assuming the response is a string */
*response_ptr = strndup(buffer, (size_t)(size *nmemb));
}
First, didn't your compiler warn you about not returning anything from this
function?
Then, a little clue from
http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTWRITEFUNCTION:
"Return the number of bytes actually taken care of. If that amount differs
from the amount passed to your function, it'll signal an error to the
library. This will abort the transfer and return CURLE_WRITE_ERROR."
