23 .TH CURLINFO_PRIVATE 3 "May 05, 2017" "libcurl 7.59.0" "curl_easy_getinfo options"
26 CURLINFO_PRIVATE \- get the private pointer
28 #include <curl/curl.h>
30 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRIVATE, char **private);
32 Pass a pointer to a char pointer to receive the pointer to the private data
33 associated with the curl handle (set with the \fICURLOPT_PRIVATE(3)\fP).
34 Please note that for internal reasons, the value is returned as a char
35 pointer, although effectively being a 'void *'.
40 CURL *curl = curl_easy_init();
42 void *pointer = 0x2345454;
43 curl_easy_setopt(curl, CURLOPT_URL, "http://example.com/foo.bin");
45 /* set the private pointer */
46 curl_easy_setopt(curl, CURLOPT_PRIVATE, pointer);
47 ret = curl_easy_perform(curl);
49 /* extract the private pointer again */
50 ret = curl_easy_getinfo(curl, CURLINFO_PRIVATE, &pointer);
52 curl_easy_cleanup(curl);
58 Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
