+# NAME
+
+CURLOPT_SSL_ENABLE_NPN - use NPN
+
+# SYNOPSIS
+
+~~~c
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSL_ENABLE_NPN, long npn);
+~~~
+
+# DESCRIPTION
+
+Deprecated since 7.86.0 Setting this option has no function.
+
+Pass a long as parameter, 0 or 1 where 1 is for enable and 0 for disable. This
+option enables/disables NPN in the SSL handshake (if the SSL backend libcurl
+is built to use supports it), which can be used to negotiate http2.
+
+# DEFAULT
+
+1, enabled
+
+# %PROTOCOLS%

+    curl_easy_setopt(curl, CURLOPT_SSL_ENABLE_NPN, 1L);
+    res = curl_easy_perform(curl);
+    curl_easy_cleanup(curl);
