fix some warnings

warning: format '%d' expects argument of type 'int', but argument 3 has type 'long unsigned int' [-Wformat=]
warning: defined but not used [-Wunused-variable]
warning: declared 'static' but never defined [-Wunused-function]
warning: suggest parentheses around '&&' within '||' [-Wparentheses}
