C++日志程序庫:RLog

jopen 11年前發布 | 14K 次閱讀 C/C++開發 C/C++

RLog是一個靈活的C++日志程序庫。RLog高度優化了不用實際輸出Log信息的分支,因此RLog可以留在發布產品中,并可以按需開啟輸出。

示例代碼:

// 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));
}
