CreateFileA is the char-version of CreateFile. Modern win32 systems use
CreateFileW though, but most provide a backward compatible wrapper for
CreateFileA.

ws2_32.dll is the Winsock 2 library, which provides sockets. This is not
even supposed to provide CreateFile.

The content of conio.h is inherently nonportable and I wouldn't even expect
it to be completely implemented. What of that do you need anyway?

You want a string literal here, i.e. double quotes. Also, you should use
initialisation instead of assignment.

Some things here:
- If you wrote that yourself, you shouldn't as g++ usually knows much
better what to link and what not to link. You should only need to add
nonstandard libraries.
- You shouldn't have to add the full path, g++ should know the path to most
libs itself.
- Why is the last line in double quotes?
