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;

typedef WCHAR TCHAR, *PTCHAR;

但在我的,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.
