VS, Implement trace functionality in Win32

Because of the trouble of calling the trace function directly in Win32, it is necessary to refer to MFC's header file, which is error-prone, and it uses the outputdebugstring function to encapsulate the trace function, the function is as follows:

Note Because the VS default character set is Unicode, where char is not equal to TCHAR, debugging is unsuccessful, and in general, in Project Properties, the character set is changed to use multibyte character sets, and char is equivalent to TCHAR:

At this point the program will still error, because there is no header file containing the _vsntprintf function , which contains <tchar.h> and <stdio.h> the header file of the OutputDebugString function is <windows.h> If you include in the header file, an exception occurs, and this is changed to include in the CPP file where the trace function is implemented.
