-The following functions return 1 on success or 0 on error: EC_GROUP_copy, EC_GROUP_set_generator, EC_GROUP_check,
-EC_GROUP_check_discriminant, EC_GROUP_get_trinomial_basis and EC_GROUP_get_pentanomial_basis.
+The following functions return 1 on success or 0 on error: EC_GROUP_copy(), EC_GROUP_set_generator(), EC_GROUP_check(),
+EC_GROUP_check_discriminant(), EC_GROUP_get_trinomial_basis() and EC_GROUP_get_pentanomial_basis().
+
+EC_GROUP_dup() returns a pointer to the duplicated curve, or NULL on error.
+
+EC_GROUP_method_of() returns the EC_METHOD implementation in use for the given curve or NULL on error.
+
+EC_GROUP_get0_generator() returns the generator for the given curve or NULL on error.
+
+EC_GROUP_get_order() returns 0 if the order is not set (or set to zero) for
+B<group> or if copying into B<order> fails, 1 otherwise.
+
+EC_GROUP_get_cofactor() returns 0 if the cofactor is not set (or is set to zero) for B<group> or if copying into B<cofactor> fails, 1 otherwise.
+
+EC_GROUP_get_curve_name() returns the curve name (NID) for B<group> or will return NID_undef if no curve name is associated.
