[INFORMATION]
The Compiler has detected a named parameter which is not used. In C parameters in function definitions must have names. In C++ parameters may have a name. If it has no name, this warning is not issued. This warning may occur in cases where the interface of a function is given, but not all parameters of all functions are really used.
void main(int i) {
}
If you are using C++, remove the name in the parameter list. If you are using C, use a name which makes clear that this parameter is intentionally not used as, for example "dummy".
