DESCRIPTION

14       Data  pointer  to  pass to the HSTS write function. If you use the CUR‐
15       LOPT_HSTSWRITEFUNCTION(3) option, this is the pointer you will  get  as
16       input in the 4th argument to the callback.
17
18       This  option does not enable HSTS, you need to use CURLOPT_HSTS_CTRL(3)
19       to do that.
