NAME
       SSL_get_peer_cert_chain - get the X509 certificate chain of the peer

SYNOPSIS
	#include <openssl/ssl.h>

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

DESCRIPTION
       SSL_get_peer_cert_chain() returns a pointer to STACKOF(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.

NOTES
       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.  If the corresponding
       session is freed, the pointer must not be used any longer.

RETURN VALUES
       The following return values can occur:

       NULL
	   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 STACKOF(X509)
	   The return value points to the certificate chain presented by the peer.
