RLog是一个灵活的C++日志程序库。RLog高度优化了不用实际输出Log信息的分支，因此RLog可以留在发布产品中，并可以按需开启输出。
示例代码：
// create custom logging channel (part of debug hierarchy) // Any subscriber to 'debug' will also pick up this sub channel, // or it can be subscribed to directly. static RLogChannel *timeChannel = DEF_CHANNEL("debug/timeStamp", Log_Debug); void func(int foo) { // log to the 'debug' channel rDebug("foo = %i", foo); int ans = 6 * 9; if(ans != 42) rWarning("ans = %i, expecting 42", ans); // log to warning channel // log to error channel rError("I'm sorry %s, I can't do that (error code %i)", name, errno); // log to custom channel // Note: time() never gets called unless there are subscribers to this message rLog(timeChannel, "the time is now %i", (int)time(NULL)); }
