+- When you invoke certain calls like unlink(), or mkdir_p() and you
+ know it is safe to ignore the error it might return (because a later
+ call would detect the failure anyway, or because the error is in an
+ error path and you thus couldn't do anything about it anyway), then
+ make this clear by casting the invocation explicitly to (void). Code
+ checks like Coverity understand that, and will not complain about
+ ignored error codes. Hence, please use this:
+
+ (void) unlink("/foo/bar/baz");
+
+ instead of just this:
+
+ unlink("/foo/bar/baz");
