[QUOTE="David Brown, post: 5152239"] Such code may be inefficient on some compilers (and with some options) - if "x" has been passed in a register, the compiler may copy it onto the stack in order for it to have an address, even though the address is not used. I have yet to see any reason to why anyone would need something other than "(void) x;" as a way to say "do nothing with x". An endless supply of suggestions of macros that mess around with "x" in weird ways does not help anyone. (Tool-specific annotations such as gcc "unused" attribute or PC-Lint annotations can be a useful addition if you use those particular tools.) [/QUOTE]
