Thank you for not top posting however your mail client is now garbling
the quoting. The e-mail you sent makes your reply look like it's a reply
I made. You may be able to fix that by hitting enter twice below
whatever you've quoted.
As I said you need to review CURLOPT_WRITEFUNCTION [1]. Your function
prototype should be:
size_t write_callback(char *ptr, size_t size, size_t nmemb, void *userdata);
Your callback must always return a value and it's not doing that. Also
you need to properly handle 0 bytes, for example if(!uiSizes) return 0.
I'm still curious what version of libcurl is actually loaded here. If
you could dump the version as I showed in my previous e-mail that would
help.
