=head1 NAME
|
||
|
|
|
||
|
|
SSL_get_tick_timeout - determine when an SSL object next needs to be ticked
|
||
|
|
|
||
|
|
=head1 SYNOPSIS
|
||
|
|
|
||
|
|
#include <openssl/ssl.h>
|
||
|
|
|
||
|
|
__owur int SSL_get_tick_timeout(SSL *s, struct timeval *tv);
|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
SSL_get_tick_timeout() determines when the SSL object next needs to perform
|
||
|
|
internal processing due to the passage of time. It is currently applicable only
|
||
|
|
to DTLS and QUIC connection SSL objects, and is not supported on other kinds of
|
||
|
|
SSL object.
|
||
|
|
|
||
|
|
Calling SSL_get_tick_timeout() results in B<*tv> being written with an amount of
|
||
|
|
time left before the SSL object needs to be ticked. If the SSL object needs to
|
||
|
|
be ticked immediately, it is set to zero; if the SSL object currently does not
|
||
|
|
need to be ticked at any point in the future, B<tv_sec> is set to -1,
|
||
|
|
representing infinity.
|
||
|
|
|
||
|
|
Note that the value output by a call to SSL_get_tick_timeout() may change as a
|
||
|
|
result of other calls to the SSL object.
|
||
|
|
|
||
|
|
Once the timeout expires, SSL_tick() should be called to handle any internal
|
||
|
|
processing which is due; for more information, see L<SSL_tick(3)>.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
Returns 1 on success and 0 on failure.
