NAME
       SSL_get_peer_cert_chain - get the X509 certificate chain of the peer

LIBRARY
       libcrypto, -lcrypto

SYNOPSIS
	#include <openssl/ssl.h>

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

DESCRIPTION
       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.

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