How to replace _wopen/_open by OpenFile

[chiyuwang]

In my programe I need to replace _open and _wopen by windows api function, I think the function OpenFile should be the one.

Are their return values are same indeed, since _open/_wopen return int, while OpenFile return HFILE, and those enum type look confusing.

Any suggestion would be appreciated.

Thank you

OpenFile is not recommended, use CreateFile instead:

HANDLE hFile=CreateFile("file.txt",GENERIC_READ | GENERIC_ALL,FILE_SHARE_READ,0,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,0);
 // Read/Write...
CloseHandle(hFile);

You will also need ReadFile and WriteFile functions
