EC_POINT_METHOD_new() creates a new EC_POINT_METHOD structure. It should be given a curve_id of elliptic curve.
EC_POINT_METHOD_free() destroys an EC_POINT_METHOD structure and frees up any memory associated with it.
EC_POINT_METHOD_curve_id() obtains the curve_id of EC_POINT_METHOD object.
EC_POINT_METHOD_get_add() and EC_POINT_METHOD_set_add() get and set the function used for calculating two EC_POINT addition respectively. This function will be called in response to the application calling EC_POINT_add(). The parameters for the function have the same meaning as for EC_POINT_add().
EC_POINT_METHOD_get_dbl() and EC_POINT_METHOD_set_dbl() get and set the function used for calculating an EC_POINT double respectively. This function will be called in response to the application calling EC_POINT_dbl(). The parameters for the function have the same meaning as for EC_POINT_dbl().
EC_POINT_METHOD_get_invert() and EC_POINT_METHOD_set_invert() get and set the function used for calculating an EC_POINT invertion respectively. This function will be called in response to the application calling EC_POINT_invert(). The parameters for the function have the same meaning as for EC_POINT_invert().
EC_POINT_METHOD_get_mul() and EC_POINT_METHOD_set_mul() get and set the function used for calculating batch EC_POINTs multiplication respectively. This function will be called in response to the application calling EC_POINTs_mul(). The parameters for the function have the same meaning as for EC_POINTs_mul().
EC_POINT_METHOD_get_scalars_mul() and EC_POINT_METHOD_set_scalars_mul() get and set the function used for calculating batch EC_POINTs scalar multiplication respectively. This function will be called in response to the application calling EC_POINT_scalars_mul(). The parameters for the function have the same meaning as for EC_POINT_scalars_mul().
EC_POINT_METHOD_get_scalar_mul() and EC_POINT_METHOD_set_scalar_mul() get and set the function used for calculating batch EC_POINTs scalar multiplication respectively. This function will be called in response to the application calling EC_POINT_scalar_mul(). The parameters for the function have the same meaning as for EC_POINT_scalar_mul().
EC_POINT_METHOD_get_strings_to_points() and EC_POINT_METHOD_set_strings_to_points() get and set the function used for converting batch strings to batch EC_POINTs respectively. This function will be called in response to the application calling EC_POINTs_from_strings(). The parameters for the function have the same meaning as for EC_POINTs_from_strings().
EC_POINT_METHOD_get_strings_to_points_scalar_mul() and EC_POINT_METHOD_set_strings_to_points_scalar_mul() get and set the function used for calculating batch EC_POINTs scalar multiplication after converting batch strings to batch EC_POINTs respectively. This function will be called in response to the application calling EC_POINTs_from_strings_scalar_mul(). The parameters for the function have the same meaning as for EC_POINTs_from_strings_scalar_mul().
EC_POINT_METHOD_new() return the newly allocated EC_POINT_METHOD object or NULL on failure.
EC_POINT_METHOD_curve_id() return the curve_id of EC_POINT_METHOD object.
All EC_POINT_METHOD_get_*() functions return the appropriate function pointer that has been set in the EC_POINT_METHOD, or NULL if no such pointer has yet been set.
All EC_POINT_METHOD_set_*() functions return 1 on success or 0 on failure.
