=head1 DESCRIPTION
|
|
|
|
SSL_SESSION_get_time() returns the time at which the session B<s> was
|
|
established. The time is given in seconds since the Epoch and therefore
|
|
compatible to the time delivered by the time() call.
|
|
|
|
SSL_SESSION_set_time() replaces the creation time of the session B<s> with
|
|
the chosen value B<tm>.
|
|
|
|
SSL_SESSION_get_timeout() returns the timeout value set for session B<s>
|
|
in seconds.
|
|
|
|
SSL_SESSION_set_timeout() sets the timeout value for session B<s> in seconds
|
|
to B<tm>.
|
|
|
|
SSL_SESSION_get_time_ex() and SSL_SESSION_set_time_ex() extended functions use
|
|
the time_t datatype instead of long to fix the Y2038 problem on systems with
|
|
64 bit time_t type.
|
|
|
|
The SSL_get_time(), SSL_set_time(), SSL_get_timeout(), and SSL_set_timeout()
|
|
functions are synonyms for the SSL_SESSION_*() counterparts.
|
|
|
|
=head1 NOTES
|
|
|
|
Sessions are expired by examining the creation time and the timeout value.
|
|
Both are set at creation time of the session to the actual time and the
|
|
default timeout value at creation, respectively, as set by
|
|
L<SSL_CTX_set_timeout(3)>.
|
|
Using these functions it is possible to extend or shorten the lifetime
|
|
of the session.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
SSL_SESSION_get_time() and SSL_SESSION_get_timeout() return the currently
|
|
valid values.
|
|
|
|
SSL_SESSION_set_time() and SSL_SESSION_set_timeout() return 1 on success.
|
|
|
|
If any of the function is passed the NULL pointer for the session B<s>,
|
|
0 is returned.
|
|
|
|
=head1 BUGS
|
|
|
|
The data type long is typically 32 bits on many systems, hence the old
|
|
functions SSL_SESSION_get_time() and SSL_SESSION_set_time() are not always
|
|
Y2038 safe.
