SSL_CTX_flush_sessions(3SSL) OpenSSL SSL_CTX_flush_sessions(3SSL)NAME
SSL_CTX_flush_sessions, SSL_flush_sessions - remove expired sessions
SYNOPSIS
#include <openssl/ssl.h>
void SSL_CTX_flush_sessions(SSL_CTX *ctx, long tm);
void SSL_flush_sessions(SSL_CTX *ctx, long tm);
DESCRIPTION
SSL_CTX_flush_sessions() causes a run through the session cache of ctx to remove sessions expired at time tm.
SSL_flush_sessions() is a synonym for SSL_CTX_flush_sessions().
NOTES
If enabled, the internal session cache will collect all sessions established up to the specified maximum number (see
SSL_CTX_sess_set_cache_size()). As sessions will not be reused ones they are expired, they should be removed from the cache to save
resources. This can either be done
automatically whenever 255 new sessions were established (see SSL_CTX_set_session_cache_mode(3)) or manually by calling
SSL_CTX_flush_sessions().
The parameter tm specifies the time which should be used for the expiration test, in most cases the actual time given by time(0) will be
used.
SSL_CTX_flush_sessions() will only check sessions stored in the internal cache. When a session is found and removed, the remove_session_cb
is however called to synchronize with the external cache (see SSL_CTX_sess_set_get_cb(3)).
RETURN VALUES SEE ALSO ssl(3), SSL_CTX_set_session_cache_mode(3), SSL_CTX_set_timeout(3), SSL_CTX_sess_set_get_cb(3)1.0.1e 2013-02-11 SSL_CTX_flush_sessions(3SSL)

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.

The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)
I see lot of ad-hoc shell scripts in our servers which don't have a shebang at the beginning .
Does this mean that it will run on any shell ?
Is it a good practice to create scripts (even ad-hoc ones) without shebang ? (16 Replies)
