NAME         top

       gnutls_certificate_type_get2 - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       gnutls_certificate_type_get2(gnutls_session_t session,
       gnutls_ctype_target_t target);

ARGUMENTS         top

       gnutls_session_t session
                   is a gnutls_session_t type.

       gnutls_ctype_target_t target
                   is a gnutls_ctype_target_t type.

DESCRIPTION         top

       This function returns the type of the certificate that a side is
       negotiated to use.  The certificate type is by default X.509, unless
       an alternative certificate type is enabled by gnutls_init() and
       negotiated during the session.

       The  target parameter specifies whether to request the negotiated
       certificate type for the client (GNUTLS_CTYPE_CLIENT), or for the
       server (GNUTLS_CTYPE_SERVER). Additionally, in P2P mode connection
       set up where you don't know in advance who will be client and who
       will be server you can use the flag (GNUTLS_CTYPE_OURS) and
       (GNUTLS_CTYPE_PEERS) to retrieve the corresponding certificate types.

       Resumed sessions will return the certificate type that was negotiated
       and used in the original session. That is, this function can be used
       to reliably determine the type of the certificate returned by

RETURNS         top

       the currently used gnutls_certificate_type_t certificate type for the
       client or the server.
