我们知道一个程序生成后会包含多个SECTION，如代码，数据等等，本文拟简单学习验证一下VS2008下生成的程序的SECTION。
使用VC的向导创建一个名为demo的console工程，修改工程属性“链接器->调试->生成映射文件”，使之生成map文件。
此时工程中只有一个简单的main函数：
int _tmain(int argc, _TCHAR* argv[])
{
return 0;
}
使用命令行查看此时生成的SECTION列表：
dumpbin /headers demo.exe >demo.txt
得到结果：
SECTION HEADER #1

有些SECTION感觉很熟悉，另外一些则比较佰生，依次看过去。
