Subject: Avoiding "unused variable" warnings
Date: Sun, 13 Jul 2003 19:32:23 +0400 [thread overview]
Message-ID: <200307131932.24015.arvidjaar@mail.ru> (raw)
I think I have seen it somewhere but forgot.
Is it possible to create a noop macro that makes compiler believe macro
arguments are used? I mean the case of debug macro that for debug off is
redefined as something like do { } while(0) but then if arguments are used
for debugging purposes only compiler emits warning. Some people do not like
it :)
TIA
