Using the CLEO-c detector at the Cornell Electron Storage Ring, we have measured inclusive and exclusive cross sections for the production of D{sup +}, D{sup 0} and D{sub s}{sup +} mesons in e{sup +}e{sup -} annihilations at 13 center-of-mass energies between 3.97 and 4.26 GeV. Exclusive cross sections are presented for final states consisting of two charm mesons (DD, D*D, D*D*, D{sub s}{sup +}D{sub s}{sup -}, D{sub s}*{sup +}D{sub s}{sup -}, and D{sub s}*{sup +}D{sub s}*{sup -}) and for processes in which the charm-meson pair is accompanied by a pion. No enhancement in any final state is observed at the energy of the Y(4260)
