| 24 | =head1 DESCRIPTION
|
|---|
| 25 |
|
|---|
| 26 | SSL_SESSION_get_time() returns the time at which the session B<s> was
|
|---|
| 27 | established. The time is given in seconds since the Epoch and therefore
|
|---|
| 28 | compatible to the time delivered by the time() call.
|
|---|
| 29 |
|
|---|
| 30 | SSL_SESSION_set_time() replaces the creation time of the session B<s> with
|
|---|
| 31 | the chosen value B<tm>.
|
|---|
| 32 |
|
|---|
| 33 | SSL_SESSION_get_timeout() returns the timeout value set for session B<s>
|
|---|
| 34 | in seconds.
|
|---|
| 35 |
|
|---|
| 36 | SSL_SESSION_set_timeout() sets the timeout value for session B<s> in seconds
|
|---|
| 37 | to B<tm>.
|
|---|
| 38 |
|
|---|
| 39 | The SSL_get_time(), SSL_set_time(), SSL_get_timeout(), and SSL_set_timeout()
|
|---|
| 40 | functions are synonyms for the SSL_SESSION_*() counterparts.
|
|---|
| 41 |
|
|---|
| 42 | =head1 NOTES
|
|---|
| 43 |
|
|---|
| 44 | Sessions are expired by examining the creation time and the timeout value.
|
|---|
| 45 | Both are set at creation time of the session to the actual time and the
|
|---|
| 46 | default timeout value at creation, respectively, as set by
|
|---|
| 47 | L<SSL_CTX_set_timeout(3)>.
|
|---|
| 48 | Using these functions it is possible to extend or shorten the lifetime
|
|---|
| 49 | of the session.
|
|---|
| 50 |
|
|---|
| 51 | =head1 RETURN VALUES
|
|---|
| 52 |
|
|---|
| 53 | SSL_SESSION_get_time() and SSL_SESSION_get_timeout() return the currently
|
|---|
| 54 | valid values.
|
|---|
| 55 |
|
|---|
| 56 | SSL_SESSION_set_time() and SSL_SESSION_set_timeout() return 1 on success.
|
|---|
| 57 |
|
|---|
| 58 | If any of the function is passed the NULL pointer for the session B<s>,
|
|---|
| 59 | 0 is returned.
