问题描述
我打开了winnt.h头文件，发现有两行：
I've opened winnt.h header file and found there this two lines:
typedef wchar_t WCHAR;
和
typedef WCHAR TCHAR, *PTCHAR;
但在我的帖子，它们之间有一些区别。
but there was comment in one of my posts that there is some difference between them. Then what is the difference?
推荐答案
如果你读完整个标题，你会发现：
If you read the entire header, you will find:
#ifdef _UNICODE
typedef WCHAR TCHAR;
#else
typedef char TCHAR;
#endif
或其他字样。
也许MS已经删除了较晚的选项。
Perhaps MS has removed the narrow option of late.
