13296403Sbdrewery=head1 DESCRIPTION
14296403Sbdrewery
15296403SbdrewerySSL_get_peer_cert_chain() returns a pointer to STACKOF(X509) certificates
16296403Sbdreweryforming the certificate chain of the peer. If called on the client side,
17296403Sbdrewerythe stack also contains the peer's certificate; if called on the server
18296403Sbdreweryside, the peer's certificate must be obtained seperately using
19296403SbdreweryL<SSL_get_peer_certificate(3)|SSL_get_peer_certificate(3)>.
20296403SbdreweryIf the peer did not present a certificate, NULL is returned.

23296403Sbdrewery
24The peer certificate chain is not necessarily available after reusing
25a session, in which case a NULL pointer is returned.
26
27The reference count of the STACKOF(X509) object is not incremented.
28If the corresponding session is freed, the pointer must not be used
29any longer.

33The following return values can occur:
34
35=over 4

37=item NULL
38
39No certificate was presented by the peer or no connection was established
40or the certificate chain is no longer available when a session is reused.
41
42=item Pointer to a STACKOF(X509)
43
44The return value points to the certificate chain presented by the peer.
