Fragmentation functions for heavy-light mesons, like the charmed D, D* mesons, are proposed. They rest on next-to-leading QCD perturbative fragmentation functions for heavy quarks, with the addition of a nonperturbative term describing phenomenologically the quark → meson transition. The cross section for production of large pT D, D* mesons at the Fermilab Tevatron is evaluated in this framework.
