29 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PRIVATE, void *pointer);
31 Pass a void * as parameter, pointing to data that should be associated with
32 this curl handle. The pointer can subsequently be retrieved using
33 \fIcurl_easy_getinfo(3)\fP with the CURLINFO_PRIVATE option. libcurl itself
34 never does nothing with this data.
41 CURL *curl = curl_easy_init();
42 struct private secrets;
44 struct private *extracted;
45 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");
47 /* store a pointer to our private struct */
48 curl_easy_setopt(curl, CURLOPT_PRIVATE, &secrets);
50 curl_easy_perform(curl);
52 /* we can extract the private pointer again too */
53 curl_easy_getinfo(curl, CURLINFO_PRIVATE, &extracted);
59 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
