SYNOPSIS

#include <gnutls/abstract.h>

int gnutls_pubkey_export_ecc_raw(gnutls_pubkey_t key, gnutls_ecc_curve_t * curve, gnutls_datum_t * x, gnutls_datum_t * y);

gnutls_pubkey_t key: Holds the public key
gnutls_ecc_curve_t * curve: will hold the curve (may be NULL)
gnutls_datum_t * x: will hold x-coordinate (may be NULL)
gnutls_datum_t * y: will hold y-coordinate (may be NULL)

DESCRIPTION
