Remove the PROTOCOLS section from the source files completely and instead generate them based on the header data in the curldown files. It also generates TLS backend information for options marked for TLS as protocol. Closes #13175

# 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
|
|
|
|
# EXAMPLE
|
|
|
|
~~~c
|
|
struct MyData {
|
|
void *custom;
|
|
};
|
|
|
|
int main(void)
|
|
{
|
|
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_HSTSWRITEFUNCTION callback */
|
|
curl_easy_setopt(curl, CURLOPT_HSTSWRITEDATA, &this);
|
|
|
|
curl_easy_perform(curl);
|
|
}
