CURLOPT_DOH_SSL_VERIFYSTATUS - verify the DoH SSL certificate's status
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_DOH_SSL_VERIFYSTATUS,
long verify);
Pass a long as parameter set to 1 to enable or 0 to disable.
This option determines whether libcurl verifies the status of the DoH (DNS-over-HTTPS) server cert using the "Certificate Status Request" TLS extension (aka. OCSP stapling).
This option is the DoH equivalent of CURLOPT_SSL_VERIFYSTATUS(3) and only affects requests to the DoH server.
If this option is enabled and the server does not support the TLS extension, the verification fails.

curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

Added in 7.76.0.
Returns CURLE_OK if OCSP stapling is supported by the SSL backend, otherwise returns CURLE_NOT_BUILT_IN.
