Linux几个调试宏__FUNCTION__ __TIME__ __LINE__ __FILE__ __DATA__

这几个宏是编译器内置的，不是在哪个头文件中包含的

直接上最简单的例子就好了，没必要多说。

源码：

[cpp] view
plaincopy

#include <stdio.h>

int main()

{

printf("The file is %s.\n",__FILE__);

printf( "The date is %s.\n", __DATE__ );

printf( "The time is %s.\n", __TIME__ );

printf( "This is line %d.\n", __LINE__ );

printf( "This function is %s.\n", __FUNCTION__ );

return 0;

}

运行结果：

[cpp] view
plaincopy

The file is macro.c.

The date is Aug 24 2012.

The time is 23:13:26.

This is line 8.

This function is main.
