I have this code for curl:
size_t write_to_string(void * ptr,size_t size,size_t nmeb,ResponseStruct * res_struct){
size_t bytes = size*nmeb;
res_struct->length += bytes;
res_struct->response = realloc(res_struct->response, res_struct->length);
strncat(res_struct->response,ptr,bytes);
return bytes;
}
char * get_url_data(char * url){
CURLcode res;
curl_easy_reset(curl);
if(curl){
curl_easy_setopt(curl, CURLOPT_URL, url);
curl_easy_setopt(curl, CURLOPT_TIMEOUT, 10);
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION,write_to_string);
ResponseStruct result;
result.response = malloc(sizeof(char));
result.response[0] = '\0';
result.length = 1;
curl_easy_setopt(curl, CURLOPT_WRITEDATA, &result);
res = curl_easy_perform(curl);
if (res) {
return NULL;
}
return result.response;
}
return NULL;
}
DateData * get_prices(DateData * prior_prices){
char * response = get_url_data("https://mtgox.com/api/0/data/getTrades.php");
char * orig = response;
if (response) {
//Stuff here just calculates price data
errno = 1;
return new_prices;
}
errno = 0;
return prior_prices;
}
The get_prices function will constantly timeout while “http://mtgox.com/api/0/data/getTrades.php” is fine in a web browser.
What is the problem?
Thank you!
