Аргументы (Arguments)

gnutls_x509_crt_t cert
                   should contain a gnutls_x509_crt_t type

       unsigned indx
                   In case multiple same OIDs exist in the extensions,
                   this specifies which to send. Use (0) to get the
                   first one.

       gnutls_datum_t * output
                   will hold the allocated extension data

       unsigned int * critical
                   will be non-zero if the extension is marked as
                   critical
