We will establish a theorem concerning value distribution of L-functions in the Selberg class, which shows how an L-function and a meromorphic function are uniquely determined by their c-values and which, as a consequence, proves a result on the uniqueness of the Riemann zeta function. The results in this paper also extend the corresponding ones in Li 6. (C) 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
