+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ const char *SSL_SESSION_get0_hostname(const SSL_SESSION *s);
+ int SSL_SESSION_set1_hostname(SSL_SESSION *s, const char *hostname);
+
+ void SSL_SESSION_get0_alpn_selected(const SSL_SESSION *s,
+                                     const unsigned char **alpn,
+                                     size_t *len);
+ int SSL_SESSION_set1_alpn_selected(SSL_SESSION *s, const unsigned char *alpn,
+                                    size_t len);
+
+=head1 DESCRIPTION
+
+SSL_SESSION_get0_hostname() retrieves the SNI value that was sent by the
+client when the session was created, or NULL if no value was sent.
+
+The value returned is a pointer to memory maintained within B<s> and
+should not be free'd.
+
+SSL_SESSION_set1_hostname() sets the SNI value for the hostname to a copy of
+the string provided in hostname.
+
+SSL_SESSION_get0_alpn_selected() retrieves the selected ALPN protocol for this
+session and its associated length in bytes. The returned value of B<*alpn> is a
+pointer to memory maintained within B<s> and should not be free'd.
+
+SSL_SESSION_set1_alpn_selected() sets the ALPN protocol for this session to the
+value in B<alpn> which should be of length B<len> bytes. A copy of the input
+value is made, and the caller retains ownership of the memory pointed to by
+B<alpn>.
+
+=head1 RETURN VALUES
+
+SSL_SESSION_get0_hostname() returns either a string or NULL based on if there
+is the SNI value sent by client.
+
+SSL_SESSION_set1_hostname() returns 1 on success or 0 on error.
+
+SSL_SESSION_set1_alpn_selected() returns 1 on success or 0 on error.

+SSL_SESSION_set1_hostname(), SSL_SESSION_get0_alpn_selected() and
+SSL_SESSION_set1_alpn_selected() were added in OpenSSL 1.1.1.
