@deftypefun {int} {gnutls_pubkey_export_ecc_raw} (gnutls_pubkey_t @var{key}, gnutls_ecc_curve_t * @var{curve}, gnutls_datum_t * @var{x}, gnutls_datum_t * @var{y})
@var{key}: Holds the public key

@var{curve}: will hold the curve (may be @code{NULL} )

@var{x}: will hold x-coordinate (may be @code{NULL} )

@var{y}: will hold y-coordinate (may be @code{NULL} )

This function will export the ECC public key's parameters found in
the given key.  The new parameters will be allocated using
@code{gnutls_malloc()}  and will be stored in the appropriate datum.

In EdDSA curves the  @code{y} parameter will be @code{NULL}  and the other parameters
will be in the native format for the curve.

This function allows for @code{NULL}  parameters since 3.4.1.

@strong{Returns:} @code{GNUTLS_E_SUCCESS}  on success, otherwise a negative error code.

@strong{Since:} 3.0
