gnutls_privkey_sign_data2 - API function

Arguments

gnutls_privkey_t signer Holds the key gnutls_sign_algorithm_t algo The signature algorithm used unsigned int flags Zero or one of gnutls_privkey_flags_t const gnutls_datum_t * data holds the data to be signed gnutls_datum_t * signature will contain the signature allocated with gnutls_malloc()
