While stereotyped repetitions are frowned upon in literature, they serve a useful purpose in manual pages, because it is easier for the user to find certain information if it is always presented in the same way. For that reason, this commit harmonizes the varying formulations in the HISTORY section about which functions, flags, etc. were added in which OpenSSL version. It also attempts to make the pod files more grep friendly by avoiding to insert line breaks between the symbol names and the corresponding version number in which they were introduced (wherever possible). Some punctuation and typographical errors were fixed on the way. Reviewed-by: Tim Hudson <tjh@openssl.org> (Merged from https://github.com/openssl/openssl/pull/7854)

=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.
