CURLOPT_HSTSREADFUNCTION(3)

curl_easy_setopt options                           CURLOPT_HSTSREADFUNCTION(3)



NAME
       CURLOPT_HSTSREADFUNCTION - read callback for HSTS hosts

SYNOPSIS
       #include <curl/curl.h>

       struct curl_hstsentry {
         char *name;
         size_t namelen;
         unsigned int includeSubDomains:1;
         char expire[18]; /* YYYYMMDD HH:MM:SS [null-terminated] */
       };

       CURLSTScode hstsread(CURL *easy, struct curl_hstsentry *sts, void *userp);

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_HSTSREADFUNCTION, hstsread);

DESCRIPTION
       Pass a pointer to your callback function, as the prototype shows above.

       This  callback function gets called by libcurl repeatedly when it popu‐
       lates the in-memory HSTS cache.

       Set the userp argument with the CURLOPT_HSTSREADDATA(3)  option  or  it
       will be NULL.

       When  this  callback  is invoked, the sts pointer points to a populated
       struct: Copy the host name to name (no longer than namelen bytes). Make
       it  null-terminated. Set includeSubDomains to TRUE or FALSE. Set expire
       to a date stamp or a zero length string for *forever* (wrong date stamp
       format might cause the name to not get accepted)

       The  callback should return CURLSTS_OK if it returns a name and is pre‐
       pared to be called again (for another host) or CURLSTS_DONE if  it  has
       no  entry  to  return. It can also return CURLSTS_FAIL to signal error.
       Returning CURLSTS_FAIL will stop the transfer from being performed  and
       make CURLE_ABORTED_BY_CALLBACK get returned.

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

DEFAULT
       NULL - no callback.

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

EXAMPLE
       {
         /* set HSTS read callback */
         curl_easy_setopt(curl, CURLOPT_HSTSREADFUNCTION, hstsread);

         /* pass in suitable argument to the callback */
         curl_easy_setopt(curl, CURLOPT_HSTSREADDATA, &hstspreload[0]);

         result = curl_easy_perform(curl);
       }

AVAILABILITY
       Added in 7.74.0

RETURN VALUE
       This will return CURLE_OK.
