// file: name of the file where the message comes from (typically __FILE__)
// line: line number where the message comes from (typically __LINE__)
// timestamp_us: for testing only - timestamp of the log in microseconds since the Unix epoch.
//               Pass 0 to use the current time.
// format: printf-style format specifier
