Parameters

[out]	radius	The radius of the star in m.
[out]	mass	The mass of the star in kg.
[out]	love_number_k2	The k_2 tidal love number of the star.
[in]	central_pressure_si	The central pressure of the star in Pa.
	eos	Pointer to the Equation of State structure.
[in]	epsrel	The relative error for the TOV solver routine

Return values

0	Success.
<0	Failure.
