CURLOPT_HSTSWRITEDATA(3) | curl_easy_setopt options | CURLOPT_HSTSWRITEDATA(3) |
NAME¶
CURLOPT_HSTSWRITEDATA - pointer passed to the HSTS write callback
SYNOPSIS¶
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HSTSWRITEDATA, void *pointer);
EXPERIMENTAL¶
Warning: this feature is early code and is marked as experimental. It can only be enabled by explicitly telling configure with --enable-hsts. You are advised to not ship this in production before the experimental label is removed.
DESCRIPTION¶
Data pointer to pass to the HSTS write function. If you use the CURLOPT_HSTSWRITEFUNCTION(3) option, this is the pointer you'll get as input in the 4th argument to the callback.
This option doesn't 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_HSTSWRITEFUNCTION callback */
curl_easy_setopt(curl, CURLOPT_HSTSWRITEDATA, &this);
curl_easy_perform(curl); }
AVAILABILITY¶
Added in 7.74.0
RETURN VALUE¶
This will return CURLE_OK.
