@var{key}: a key

@var{curve}: will hold the curve

@var{x}: will hold the x-coordinate

@var{y}: will hold the y-coordinate

@var{k}: will hold the private key

This function will export the ECC private key's parameters found
in the given structure. 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.

@strong{Returns:} On success, @code{GNUTLS_E_SUCCESS}  (0) is returned, otherwise a
negative error value.

@strong{Since:} 3.0
