1.代码

#define ACE_NTRACE 0

#include <iostream>

#include <ace/Log_Msg.h>

#define DEBUG_PREFIX ACE_TEXT ("DEBUG%I")

#define MYDEBUG(FMT, ...)        \

    ACE_DEBUG( (LM_DEBUG,        \

        DEBUG_PREFIX FMT    \

         __VA_ARGS__))

int main(int argc, char* argv[])

{

    ACE_TRACE("main");

    MYDEBUG( ACE_TEXT("Good night\n"));   

    return 0;

}

2. 结果

(3073735232) calling main in file `de.cpp' on line 14

DEBUG    Goodnight

(3073735232) leaving main

 

tips: 要想%I生效必须把高亮加上否则不生效
