=head1 NAME
|
|
|
|
SSL_dup, SSL_new, SSL_up_ref - create an SSL structure for a connection
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/ssl.h>
|
|
|
|
SSL *SSL_dup(SSL *s);
|
|
SSL *SSL_new(SSL_CTX *ctx);
|
|
int SSL_up_ref(SSL *s);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
SSL_new() creates a new B<SSL> structure which is needed to hold the
|
|
data for a TLS/SSL connection. The new structure inherits the settings
|
|
of the underlying context B<ctx>: connection method,
|
|
options, verification settings, timeout settings. An B<SSL> structure is
|
|
reference counted. Creating an B<SSL> structure for the first time increments
|
|
the reference count. Freeing it (using SSL_free) decrements it. When the
|
|
reference count drops to zero, any memory or resources allocated to the B<SSL>
|
|
structure are freed.
|
|
|
|
SSL_up_ref() increments the reference count for an
|
|
existing B<SSL> structure.
|
|
|
|
SSL_dup() duplicates an existing B<SSL> structure into a new allocated one. All
|
|
settings are inherited from the original B<SSL> structure. Dynamic data (i.e.
|
|
existing connection details) are not copied, the new B<SSL> is set into an
|
|
initial accept (server) or connect (client) state.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
The following return values can occur:
|
|
|
|
=over 4
|
|
|
|
=item NULL
|
|
|
|
The creation of a new SSL structure failed. Check the error stack to
|
|
find out the reason.
|
|
|
|
=item Pointer to an SSL structure
|
|
|
|
The return value points to an allocated SSL structure.
|
|
|
|
SSL_up_ref() returns 1 for success and 0 for failure.
