Search for CP Violation in the Decays ${D^{\pm} \to   K^0_{\scriptscriptstyle S} K^\pm$, ${D_s^{\pm} \to K^0_{\scriptscriptstyle S}   K^\pm$, and ${D_s^{\pm} \to K^0_{\scriptscriptstyle S} \pi^\pm$
  We report on a search for CP violation in the decays K^0_{\scriptscriptstyle S} K^\pm$, ${D_s^{\pm} \to K^0_{\scriptscriptstyle S} K^\pm$, and ${D_s^{\pm} \to K^0_{\scriptscriptstyle S} \pi^\pm$ using a data set corresponding to an integrated luminosity of $469\,\invfb$ collected with the BaBar detector at the PEP-II asymmetric energy \epem storage rings. The CP-violating decay rate asymmetries $A_{CP}$ are determined to be $(+0.13 \pm 0.36 \stat \pm 0.25 \syst)%$, $(-0.05 \pm 0.23 \stat \pm 0.24 \syst)%$, and $(+0.6 \pm 2.0 \stat \pm 0.3 \syst)%$, respectively for the three modes, before correction for the relevant K^0_{\scriptscriptstyle S} asymmetry. After this correction, all the measurements are consistent with zero within one standard deviation. These are currently the most precise measurements of these asymmetries.
