SSL_get_peer_cert_chain(3)
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(
	  SSL *ssl );

DESCRIPTION
  The SSL_get_peer_cert_chain() function 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
  the SSL_get_peer_certificate() function. 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.

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.
