void some_fubar(int a, int b)
{
int NOT_USED;
return(a*b);
}
In the above example NOT_USED would be an unreferenced local variable.
Basically the function has a parameter or declares a local variable that is not used in it.
{
int NOT_USED;
return(a*b);

That meen that you have allocated space on the stack for a variable that never was used in the function. It doesn''t really matter, if you remove the variables the program will still run as fine it did with them. Even better as you will not pollute the stack as much. Example:
Update GameDev.net system time campaign - success at last
void foo(){ int bar; // warning C4101: bar'' : unreferenced local variable} Update GameDev.net system time campaign - success at last
