SSL_CTX_set_timeout(3)
NAME
  SSL_CTX_set_timeout, SSL_CTX_get_timeout - Manipulate timeout values for
  session caching

SYNOPSIS
  #include <openssl/ssl.h>

  long SSL_CTX_set_timeout(
	  SSL_CTX *ctx,
	  long t );

  long SSL_CTX_get_timeout(
	  SSL_CTX *ctx );

DESCRIPTION
  The SSL_CTX_set_timeout() function sets the timeout for newly created
  sessions for ctx to t.  The timeout value t must be given in seconds.

  The SSL_CTX_get_timeout() function returns the currently set timeout value
  for ctx.

NOTES
  Whenever a new session is created, it is assigned a maximum lifetime.	 This
  lifetime is specified by storing the creation time of the session and the
  timeout value valid at this time. If the actual time is later than creation
  time plus timeout, the session is not reused.

  Due to this realization, all sessions behave according to the timeout value
  valid at the time of the session negotiation. Changes of the timeout value
  do not affect already established sessions.

  The expiration time of a single session can be modified using the
  SSL_SESSION_get_time() family of functions.

  Expired sessions are removed from the internal session cache whenever
  SSL_CTX_flush_sessions() is called, either directly by the application or
  automatically (see  SSL_CTX_set_session_cache_mode(3)).

  The default value for session timeout is decided on a per protocol basis.
  (See SSL_get_default_timeout().  All currently supported protocols have the
  same default timeout value of 300 seconds.

RETURN VALUES
  The SSL_CTX_set_timeout() function returns the previously set timeout
  value.

  SSL_CTX_get_timeout() function returns the currently set timeout value.
