CURLINFO_PRIVATE - get the private pointer
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRIVATE, char
Pass a pointer to a char pointer to receive the pointer to the private data
associated with the curl handle (set with the CURLOPT_PRIVATE(3)).
Please note that for internal reasons, the value is returned as a char
pointer, although effectively being a 'void *'.
CURL *curl = curl_easy_init();
void *pointer = 0x2345454;
curl_easy_setopt(curl, CURLOPT_URL, "http://example.com/foo.bin");
/* set the private pointer */
curl_easy_setopt(curl, CURLOPT_PRIVATE, pointer);
ret = curl_easy_perform(curl);
/* extract the private pointer again */
ret = curl_easy_getinfo(curl, CURLINFO_PRIVATE, &pointer);
Added in 7.10.3
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
