Abstract
We establish a generalization of the Dunkl--Williams inequality and its inverse in the framework of Hilbert -modules and characterize the equality case. As applications, we get some new results and some known results due to Pe\v{c}ari\'c and Raji\'c [Linear Algebra Appl. 425 (2007), no. 1, 16--25].
