We calculate the fragmentation function for a charm quark to decay inclusively into S-wave charmonium states, including relativistic and binding energy corrections in powers of the quark relative velocity v. We also use these fragmentation functions to estimate their contribution to the production rate of {eta}{sub c} and J/{psi} in Z{sup 0} decay. These corrections contribute about 38{percent} to the integrated c{r_arrow}J/{psi}+X fragmentation. For {eta}{sub c}, these corrections are found to be small. {copyright} {ital 1997} {ital The American Physical Society}
