SSL_CTX_ctrl(3) OpenSSL SSL_CTX_ctrl(3)NAME
SSL_CTX_ctrl, SSL_CTX_callback_ctrl, SSL_ctrl, SSL_callback_ctrl - internal handling functions for SSL_CTX and SSL objects
LIBRARY
libcrypto, -lcrypto
SYNOPSIS
#include <openssl/ssl.h>
long SSL_CTX_ctrl(SSL_CTX *ctx, int cmd, long larg, void *parg);
long SSL_CTX_callback_ctrl(SSL_CTX *, int cmd, void (*fp)());
long SSL_ctrl(SSL *ssl, int cmd, long larg, void *parg);
long SSL_callback_ctrl(SSL *, int cmd, void (*fp)());
DESCRIPTION
The SSL_*_ctrl() family of functions is used to manipulate settings of the SSL_CTX and SSL objects. Depending on the command cmd the
arguments larg, parg, or fp are evaluated. These functions should never be called directly. All functionalities needed are made available
via other functions or macros.
RETURN VALUES
The return values of the SSL*_ctrl() functions depend on the command supplied via the cmd parameter.

SSL_set_session(3) OpenSSL SSL_set_session(3)NAME
SSL_set_session - set a TLS/SSL session to be used during TLS/SSL connect
LIBRARY
libcrypto, -lcrypto
SYNOPSIS
#include <openssl/ssl.h>
int SSL_set_session(SSL *ssl, SSL_SESSION *session);
DESCRIPTION
SSL_set_session() sets session to be used when the TLS/SSL connection is to be established. SSL_set_session() is only useful for TLS/SSL
clients. When the session is set, the reference count of session is incremented by 1. If the session is not reused, the reference count is
decremented again during SSL_connect(). Whether the session was reused can be queried with the SSL_session_reused(3) call.
If there is already a session set inside ssl (because it was set with SSL_set_session() before or because the same ssl was already used for
a connection), SSL_SESSION_free() will be called for that session.
NOTES
SSL_SESSION objects keep internal link information about the session cache list, when being inserted into one SSL_CTX object's session
cache. One SSL_SESSION object, regardless of its reference count, must therefore only be used with one SSL_CTX object (and the SSL objects
created from this SSL_CTX object).
RETURN VALUES
The following return values can occur:
0 The operation failed; check the error stack to find out the reason.
1 The operation succeeded.

Introduction
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:
$ ls -ld /usr/bin /usr/bin/cat
drwxrwxr-x 3 root bin 8704 Sep 23 2004 /usr/bin

sort -nr --key=1 ....

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.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)

Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
