     17 # NAME
     18 
     19 CURLOPT_HSTSWRITEDATA - pointer passed to the HSTS write callback
     20 
     21 # SYNOPSIS
     22 
     23 ~~~c
     24 #include <curl/curl.h>
     25 
     26 CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HSTSWRITEDATA, void *pointer);
     27 ~~~
     28 
     29 # DESCRIPTION
     30 
     31 Data *pointer* to pass to the HSTS write function. If you use the
     32 CURLOPT_HSTSWRITEFUNCTION(3) option, this is the pointer you get as
     33 input in the fourth argument to the callback.
     34 
     35 This option does not enable HSTS, you need to use CURLOPT_HSTS_CTRL(3) to
     36 do that.
