From dc8cfa55da8c21e0b3290c29677a9d05c0a3e595 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 1 Sep 2008 12:46:50 +0100 Subject: sfc: Use explicit bool for boolean variables, parameters and return values Replace (cond ? 1 : 0) with cond or !!cond as appropriate, and (cond ? 0 : 1) with !cond. Remove some redundant boolean temporaries. Rename one field that looks like a flag but isn't.
