CreateFile library error

[DSMan195276]

I'd recommend using Declare CustomType Library instead. Or, if you want to avoid compilation errors entirely, declare the DLL that contains that function rather than trying to use the headers.

I would definitely not recommend that. In this case all `CustomType` would do is allow you to ignore the C++ function declaration already present from the header, you should only do that if it's necessary. In this case, the compilation error is because eoredson had a legitimate bug in his program and as a consequence it would not work on 64-bit. Using `CustomType` would have allowed it to compile, but not actually fix the bug. It provides a false sense of security and you shouldn't be using it unless actually necessary.

I need to know because I might have the same problem with GetFileAttribute as I do with CreateFile..

Again, read the Microsoft documentation, it tells you the exact information you're looking for. The GetFileAttributeA function documentation is here. The provided syntax is this:

Code: (Select All)

DWORD GetFileAttributesA(
  [in] LPCSTR lpFileName
);

The return type is a `DWORD` and the parameter is an `LPCSTR`.
