CURLOPT_HSTSREADDATA(3)             libcurl            CURLOPT_HSTSREADDATA(3)

NAME
       CURLOPT_HSTSREADDATA - pointer passed to the HSTS read callback

SYNOPSIS
       #include <curl/curl.h>

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

DESCRIPTION
       Data pointer to pass to the HSTS read function. If you use the
       CURLOPT_HSTSREADFUNCTION(3) option, this is the pointer you will get as
       input in the 3rd argument to the callback.

       This option does not enable HSTS, you need to use CURLOPT_HSTS_CTRL(3)
       to do that.

DEFAULT
       NULL

PROTOCOLS
       This feature is only used for HTTP(S) transfer.

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

         /* pass pointer that gets passed in to the
            CURLOPT_HSTSREADFUNCTION callback */
         curl_easy_setopt(curl, CURLOPT_HSTSREADDATA, &this);

         curl_easy_perform(curl);
       }

AVAILABILITY
       Added in 7.74.0

       This will return CURLE_OK.
