CURLOPT_PRIVATE(3)         curl_easy_setopt options         CURLOPT_PRIVATE(3)

NAME
       CURLOPT_PRIVATE - store a private pointer

SYNOPSIS
       #include <curl/curl.h>

       CURLcode    curl_easy_setopt(CURL    *handle,   CURLOPT_PRIVATE,   void
       *pointer);

DESCRIPTION
       Pass a void * as parameter, pointing to data that should be  associated
       with this curl handle.  The pointer can subsequently be retrieved using
       curl_easy_getinfo(3) with the CURLINFO_PRIVATE option.  libcurl  itself
       never does nothing with this data.

DEFAULT
       NULL

PROTOCOLS

EXAMPLE
       CURL *curl = curl_easy_init();
       struct private secrets;
       if(curl) {
         struct private *extracted;
         curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

         /* store a pointer to our private struct */
         curl_easy_setopt(curl, CURLOPT_PRIVATE, &secrets);

         curl_easy_perform(curl);

         /* we can extract the private pointer again too */
         curl_easy_getinfo(curl, CURLINFO_PRIVATE, &extracted);
       }
