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,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.
