5 SSL_dup, SSL_new, SSL_up_ref - create an SSL structure for a connection
9 #include <openssl/ssl.h>
12 SSL *SSL_new(SSL_CTX *ctx);
13 int SSL_up_ref(SSL *s);
17 SSL_new() creates a new B<SSL> structure which is needed to hold the
18 data for a TLS/SSL connection. The new structure inherits the settings
19 of the underlying context B<ctx>: connection method,
20 options, verification settings, timeout settings. An B<SSL> structure is
21 reference counted. Creating an B<SSL> structure for the first time increments
22 the reference count. Freeing it (using SSL_free) decrements it. When the
23 reference count drops to zero, any memory or resources allocated to the B<SSL>
26 SSL_up_ref() increments the reference count for an
27 existing B<SSL> structure.
29 SSL_dup() duplicates an existing B<SSL> structure into a new allocated one. All
30 settings are inherited from the original B<SSL> structure. Dynamic data (i.e.
31 existing connection details) are not copied, the new B<SSL> is set into an
32 initial accept (server) or connect (client) state.
36 The following return values can occur:
42 The creation of a new SSL structure failed. Check the error stack to
45 =item Pointer to an SSL structure
47 The return value points to an allocated SSL structure.
49 SSL_up_ref() returns 1 for success and 0 for failure.
