klog_set_loglevel(KLOG_TRACE);
klog_trace("Hi!");
klog_debug("This is a simple log library.");
klog_info("It is very lightweight and easy to use.");
klog_warn("You can print logs to a console or a file.");
klog_error("Try out.");
klog_fatal(":-)");

If you want to use file log, pass a file path as a parameter

klog_init("./log");
klog_set_loglevel(KLOG_TRACE);
klog_info("This is info log.");
klog_warn("This is warn log.");
