* // the message. This example prints to the console. One caveat: msg
* // is a static string and will be over-written at the next call to ULOG.
* // You may print it or copy it, but saving a pointer to it will lead to
* // confusion and astonishment.
* //
* void my_console_logger(ulog_level_t level, const char *msg) {
* printf("%s [%s]: %s\n",
* get_timestamp(),
* ulog_level_name(level),
* msg);
* }
*
* int main() {
* ULOG_INIT();
*
* // log to the console messages that are WARNING or more severe. You
* // can re-subscribe at any point to change the severity level.
* ULOG_SUBSCRIBE(my_console_logger, ULOG_WARNING);
*
* // log to a file messages that are DEBUG or more severe
* ULOG_SUBSCRIBE(my_file_logger, ULOG_DEBUG);
*
* int arg = 42;
* ULOG_INFO("Arg is %d", arg); // logs to file but not console
