NAME         top

       gnutls_certificate_get_peers - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       const gnutls_datum_t * gnutls_certificate_get_peers(gnutls_session_t
       session, unsigned int * list_size);

ARGUMENTS         top

       gnutls_session_t          session
                   is a gnutls session

       unsigned int * list_size
                   is the length of the certificate list (may be NULL)

DESCRIPTION         top

       Get the peer's raw certificate (chain) as sent by the peer.  These
       certificates are in raw format (DER encoded for X.509).  In case of a
       X.509 then a certificate list may be present.  The list is provided
       as sent by the server; the server must send as first certificate in
       the list its own certificate, following the issuer's certificate,
       then the issuer's issuer etc. However, there are servers which
       violate this principle and thus on certain occasions this may be an
       unsorted list.

       In resumed sessions, this function will return the peer's certificate
       list as used in the first/original session.

RETURNS         top

       a pointer to a gnutls_datum_t containing the peer's certificates, or
       NULL in case of an error or if no certificate was used.
