       SSL_get_peer_cert_chain - get the X509 certificate chain of the peer

       libcrypto, -lcrypto

	#include <openssl/ssl.h>

	STACK_OF(X509) *SSL_get_peer_cert_chain(const SSL *ssl);

       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 SSL_get_peer_certificate(3).  If the peer did not present a certificate,
       NULL is returned.

       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 STACK_OF(X509) object is not incremented.  If the corresponding
       session is freed, the pointer must not be used any longer.

       The following return values can occur:

	   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.

       Pointer to a STACK_OF(X509)
	   The return value points to the certificate chain presented by the peer.
