  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
non-perturbative term describing phenomenologically the quark --> meson
transition. The cross section for production of large p_T D, D^* mesons at the
Tevatron is evaluated in this framework.
