Based on the recently developed framework of Curci, Furmanski, and Petronzio, we derive the photon structure functions in quantum chromodynamics (QCD). Then we perform QCD calculations for the azimuthal asymmetries of jets in two-photon processes. We find that in contrast to the case of lepton-hadron scatterings, the deep-inelastic e/sup +/e/sup -/ reaction via two-photon exchange is expected to show cleaner signatures for the azimuthal asymmetries as a result of enhanced QCD effects. We suggest that these will serve as useful tests of QCD.
