# 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 *'.
