# NAME
|
|
|
|
CURLOPT_HSTSWRITEDATA - pointer passed to the HSTS write callback
|
|
|
|
# SYNOPSIS
|
|
|
|
~~~c
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HSTSWRITEDATA, void *pointer);
|
|
~~~
|
|
|
|
# DESCRIPTION
|
|
|
|
Data *pointer* to pass to the HSTS write function. If you use the
|
|
CURLOPT_HSTSWRITEFUNCTION(3) option, this is the pointer you get as
|
|
input in the fourth argument to the callback.
|
|
|
|
This option does not enable HSTS, you need to use CURLOPT_HSTS_CTRL(3) to
|
|
do that.
|
|
|
|
# DEFAULT
|
|
|
|
NULL
