You MUST NOT free 36 - it gets freed when you call curl_easy_cleanup(3) on the corresponding curl 37 handle. 38 39 # %PROTOCOLS% 40 41 # EXAMPLE 42 43 ~~~c 44 int main(void) 45 { 46 CURL *curl = curl_easy_init(); 47 if(curl) { 48 CURLcode res; 49 curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); 50 curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L); 51 res = curl_easy_perform(curl); 52 if(res == CURLE_OK) { 53 char *url = NULL; 54 curl_easy_getinfo(curl, CURLINFO_EFFECTIVE_URL, &url); 55 if(url) 56 printf("Redirect to: %s\n", url); 57 } 58 curl_easy_cleanup(curl); 59 } 60 } 61 ~~~ 62 63 # %AVAILABILITY% 64 65 # RETURN VALUE 66 67 curl_easy_getinfo(3) returns a CURLcode indicating success or error. 68 69 CURLE_OK (0) means everything was OK, non-zero means an error occurred, see 70 libcurl-errors(3).
