SSL_get_peer_cert_chain() returns a pointer to STACKOF(X509) certificates

SSL_get_peer_cert_chain() returns a pointer to STACK_OF(X509) certificates

forming the certificate chain of the peer. If called on the client side,

the stack also contains the peer's certificate; if called on the server

side, the peer's certificate must be obtained separately using

The peer certificate chain is not necessarily available after reusing

a session, in which case a NULL pointer is returned.

The reference count of the STACKOF(X509) object is not incremented.

The reference count of the STACK_OF(X509) object is not incremented.

If the corresponding session is freed, the pointer must not be used

any longer.

No certificate was presented by the peer or no connection was established

or the certificate chain is no longer available when a session is reused.

=item Pointer to a STACKOF(X509)

The return value points to the certificate chain presented by the peer.
