=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.
