VC中可以自定义编译输出消息

转自【/article/1415716.html】





#pragma message("Insert User-defined Information here!")

但是这样没有文件和行数信息，不能定位。

使用如下方式可以定位：

[cpp]
view plaincopyprint?

// put the following code in header file or at the beginning of the source file.

#define __STR2__(x) #x
#define __STR1__(x) __STR2__(x)

#define __LOC__ __FILE__ "("__STR1__(__LINE__)") : Warning Msg: "

// output the user-define information in the source file.

#pragma message(__LOC__"User-defined Information")

// put the following code in header file or at the beginning of the source file.
#define __STR2__(x) #x
#define __STR1__(x) __STR2__(x)
#define __LOC__ __FILE__ "("__STR1__(__LINE__)") : Warning Msg: "

// output the user-define information in the source file.
#pragma message(__LOC__"User-defined Information")
