I like this if there's more than one boolean arg. If there's only one, I'm
ambivalent.
// In some header:
void foo (int, int, bool = -1);
// In some .c file:
void foo (int x, int y, bool bar_p /* = false */)
I think this is a good idea -- I've sometimes been puzzled by only looking at
the defn, because it happened to be in the same file as the call site I was
examining.
As has been mentioned, this does allow the decl and in-def comment to diverge.
How about something like:
void foo (int, T = ...);
void foo (int x, T y /* = default */)
{
}
?
