Hello!
I have used libcurl in vs2005 for cpp applications and I'm happy:)
But when i started writing a service using .net technology some problems
aroused.
this is the source:
// this code is called from System::Threading::Thread
std::vector<char> url(256);
std::vector <char> ebuf(100);
m_buf = new std::vector<char>;
sprintf(&url[0], "ya.ru");
int err = curl_global_init(CURL_GLOBAL_ALL);
if(err) return -1;
CURL * chnd = curl_easy_init();
err = curl_easy_setopt(chnd, CURLOPT_ERRORBUFFER, &ebuf[0]);
if(err) return -1;
err = curl_easy_setopt(chnd, CURLOPT_WRITEFUNCTION, write_data);
if(err) return -1;
err = curl_easy_setopt(chnd, CURLOPT_URL, &url[0]);
if(err) return -1;
err = curl_easy_perform(chnd);
//callback function
size_t dataloader::write_data(void *buffer, size_t size, size_t nmemb, void
*userp){
std::vector<char> buf(size*nmemb+bsize); //
<<<<<<<----------------------------here in debugger i see that buffer
value is <undefined value>
memcpy(&(buf)[bsize], buffer, size*nmemb); //
<<<<<<<-----------------------------and here it crashes (read violation)
return size*nmemb;
};
I think that it's because of /clr but anyway... is it possibly to use
libcurl in this case?
Thank You in advance,
with best regards
Mike
