C++日志程序库:RLog

分享到:

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));
}
