SSL_CTX_set_ssl_version(3SSL) OpenSSL SSL_CTX_set_ssl_version(3SSL)NAME
SSL_CTX_set_ssl_version, SSL_set_ssl_method, SSL_get_ssl_method - choose a new TLS/SSL method
SYNOPSIS
#include <openssl/ssl.h>
int SSL_CTX_set_ssl_version(SSL_CTX *ctx, const SSL_METHOD *method);
int SSL_set_ssl_method(SSL *s, const SSL_METHOD *method);
const SSL_METHOD *SSL_get_ssl_method(SSL *ssl);
DESCRIPTION
SSL_CTX_set_ssl_version() sets a new default TLS/SSL method for SSL objects newly created from this ctx. SSL objects already created with
SSL_new(3) are not affected, except when SSL_clear(3) is being called.
SSL_set_ssl_method() sets a new TLS/SSL method for a particular ssl object. It may be reset, when SSL_clear() is called.
SSL_get_ssl_method() returns a function pointer to the TLS/SSL method set in ssl.
NOTES
The available method choices are described in SSL_CTX_new(3).
When SSL_clear(3) is called and no session is connected to an SSL object, the method of the SSL object is reset to the method currently set
in the corresponding SSL_CTX object.
RETURN VALUES
The following return values can occur for SSL_CTX_set_ssl_version() and SSL_set_ssl_method():
0 The new choice failed, check the error stack to find out the reason.
1 The operation succeeded.

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:

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 ?
