criticalf

tracef("is number %d", 1);
infof("is number %d", 2);
errorf("is number %d", 3);
criticalf("is number %d", 4);
fatalf("is number %d", 5);

The second version of the function logs data to the sharedLog in a printf-style manner.

In order for the resulting log message to be logged the LogLevel must be greater or equal than the LogLevel of the sharedLog and must be greater or equal than the global LogLevel. Additionally the LogLevel must be greater or equal than the LogLevel of the stdSharedLogger.

tracef(false, "is number %d", 1);
infof(false, "is number %d", 2);
errorf(true, "is number %d", 3);
criticalf(true, "is number %d", 4);
fatalf(someFunct(), "is number %d", 5);
