PK_CURVE_make_bcurve_t

typedef int PK_CURVE_make_bcurve_t;

Used in:

PK_CURVE_make_bcurve_2
PK_CURVE_make_bcurve_res_t

A status value to be returned when creating a B-curve representation of a
curve.

It has the values:

    PK_CURVE_make_bcurve_exact_c      The resultant B-curve is exactly
                                      coincident with the given 'curve'.
    PK_CURVE_make_bcurve_approx_c     The resultant B-curve is an
                                      approximation of the given 'curve', and
                                      the maximum deviation between the
                                      B-curve and 'curve' is less than or
                                      equal to the supplied 'tolerance'.
    PK_CURVE_make_bcurve_loose_c      The resultant B-curve is an
                                      approximation of the given 'curve', but
                                      the maximum deviation between the
                                      B-curve and 'curve' is greater than the
                                      supplied 'tolerance'.

    The following tokens are returned only from PK_CURVE_make_bcurve_array:

    PK_CURVE_make_bcurve_bad_cont_c   Failed to create an equivalent B-curve
                                      because the requested 'continuity' is
                                      incompatible with the 'degree'.
    PK_CURVE_make_bcurve_bad_int_c    Input 'range' has zero extent or
                                      unsupported value.
    PK_CURVE_make_bcurve_failed_c     Failed to create an equivalent B-curve
                                      due to an internal error.
