+# NAME
+
+CURLINFO_PRIVATE - get the private pointer
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRIVATE, char **private);
+~~~
+
+# DESCRIPTION
+
+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 *'.

+
+~~~c
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode res;
+    void *pointer = (void *)0x2345454;
+    curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/foo.bin");
+
+    /* set the private pointer */
+    curl_easy_setopt(curl, CURLOPT_PRIVATE, pointer);
+    res = curl_easy_perform(curl);
+
+    /* extract the private pointer again */
+    res = curl_easy_getinfo(curl, CURLINFO_PRIVATE, &pointer);
+
+    if(res)
+      printf("error: %s\n", curl_easy_strerror(res));
+
+    curl_easy_cleanup(curl);
+  }
+}
