=head1 NAME
|
|
|
|
DTLSv1_get_timeout - determine when a DTLS SSL object next needs a timeout
|
|
event to be handled
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
int DTLSv1_get_timeout(SSL *s, struct timeval *tv);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
DTLSv1_get_timeout() can be used on a DTLS SSL object to determine when the
|
|
SSL object next needs to perform internal processing due to the passage of time.
|
|
|
|
Calling DTLSv1_get_timeout() results in I<*tv> being written with an amount of
|
|
time left before the SSL object needs have DTLSv1_handle_timeout() called on it.
|
|
If the SSL object needs to be ticked immediately, I<*tv> is zeroed and the
|
|
function succeeds, returning 1. If no timeout is currently active, this function
|
|
returns 0.
|
|
|
|
This function is only applicable to DTLS objects. It fails if called on
|
|
any other kind of SSL object.
|
|
|
|
Note that the value output by a call to DTLSv1_get_timeout() may change as a
|
|
result of other calls to the SSL object.
|
|
|
|
Once the timeout expires, DTLSv1_handle_timeout() should be called to handle any
|
|
internal processing which is due; for more information, see
|
|
L<DTLSv1_handle_timeout(3)>.
|
|
|
|
L<SSL_get_tick_timeout(3)> supersedes all use cases for this this function and
|
|
may be used instead of it.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
On success, writes a duration to I<*tv> and returns 1.
|
|
|
|
Returns 0 on failure, or if no timeout is currently active.
