From 32 bit to 64bit

[bitcoin]

Hello
i try to re-write my program to work in native 64bit.

Many errors with memory access, because many code such as

Code: [Select]

functionAddres = (DWORD)GetProcAddress(curDllModule, pFunction);In 64bit address may be greater then DWORD value.. Can I change all pointers to DWORD_PTR ? Or I must use ULONG?

[Pelle]

DWORD_PTR should work fine. Also works with ULONG_PTR. ULONG is same as DWORD, so not much help there...

Thank you Pelle.

DWORD64 is equ DWORD_PTR in 64bit? Or this is different data types?

It's effectively the same thing. Using DWORD_PTR for an address type is *maybe* more informative, but who knows...?
