# SSL\_get\_default\_timeout(3ssl)

get default session timeout value

## NAME

SSL\_get\_default\_timeout - get default session timeout value

## SYNOPSIS

```
 #include <openssl/ssl.h>
 long SSL_get_default_timeout(const SSL *ssl);
```

## DESCRIPTION

**SSL\_get\_default\_timeout()** returns the default timeout value assigned to SSL\_SESSION objects negotiated for the protocol valid for **ssl**.

## NOTES

Whenever a new session is negotiated, it is assigned a timeout value, after which it will not be accepted for session reuse. If the timeout value was not explicitly set using **SSL\_CTX\_set\_timeout**(3), the hardcoded default timeout for the protocol will be used.

**SSL\_get\_default\_timeout()** return this hardcoded value, which is 300 seconds for all currently supported protocols.

## RETURN VALUES

See description.
