26 SSL_SESSION_get0_hostname() retrieves the SNI value that was sent by the
27 client when the session was created, or NULL if no value was sent.
29 The value returned is a pointer to memory maintained within B<s> and
32 SSL_SESSION_set1_hostname() sets the SNI value for the hostname to a copy of
33 the string provided in hostname.
35 SSL_SESSION_get0_alpn_selected() retrieves the selected ALPN protocol for this
36 session and its associated length in bytes. The returned value of B<*alpn> is a
37 pointer to memory maintained within B<s> and should not be free'd.
39 SSL_SESSION_set1_alpn_selected() sets the ALPN protocol for this session to the
40 value in B<alpn> which should be of length B<len> bytes. A copy of the input
41 value is made, and the caller retains ownership of the memory pointed to by
46 SSL_SESSION_get0_hostname() returns either a string or NULL based on if there
47 is the SNI value sent by client.
49 SSL_SESSION_set1_hostname() returns 1 on success or 0 on error.
51 SSL_SESSION_set1_alpn_selected() returns 1 on success or 0 on error.
