14 SSL_get_peer_cert_chain() returns a pointer to STACKOF(X509)
15 certificates forming the certificate chain of the peer. If called on
16 the client side, the stack also contains the peer's certificate; if
17 called on the server side, the peer's certificate must be obtained
18 separately using SSL_get_peer_certificate(3). If the peer did not
19 present a certificate, NULL is returned.
20
22 The peer certificate chain is not necessarily available after reusing a
23 session, in which case a NULL pointer is returned.
24
25 The reference count of the STACKOF(X509) object is not incremented. If
26 the corresponding session is freed, the pointer must not be used any
27 longer.
28
30 The following return values can occur:
31
32 NULL
33 No certificate was presented by the peer or no connection was
34 established or the certificate chain is no longer available when a
35 session is reused.
36
37 Pointer to a STACKOF(X509)
38 The return value points to the certificate chain presented by the
39 peer.
