       gnutls_certificate_get_peers - API function


       #include <gnutls/gnutls.h>

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


       gnutls_session_t          session
                   is a gnutls session

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


       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.


       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.
