* Macro: DPRINTF()
|

|

* Usage: 调用格式与printf()一致，支持变长参数表，例子如下：
|
||
*
|
||
* #include "debug.h"
|
||
* ...
|
||
* int errcode;
|
||
* char message[] = "xxx failed!";
|
||
* ...
|
||
* DPRINTF("Debug message: errcode=%d\n", errcode);
|
||
* DPRINTF("Debug message: $s\n", message);
|
||
* exit(errcode);
|
||
*
|
||
* 在发布版中定义NDEBUG宏可以清除所有DPRINTF()信息
|
||
* 注：宏NDEBUG源自C语言惯例
