Killboy Posted March 29, 2008 Posted March 29, 2008 Heya I just tried coding something in C++ which exports a function in a dll that takes an ULONGLONG param. Now I was trying to create a MASM inc file for the prototypes. The problem is that if I use Function PROTO STDCALL Value : QWORD it seems to swap the lo and hi values. This seems to be a problem with C++ where the low part of the qword is located at [offset] and the high part at [offset+4]. (Offset being the address of the qword) AFAIK it's the other way around in MASM so I was looking for a data type that would behave the same... Instead of having to use: Function PROTO STDCALL ValueLow : DWORD, ValueHigh : DWORD Or am I wrong and MASM does it the same way ? I've just seen a few sources where it is done differently, but I havent worked with QWORDs very much, let alone MASM Thanks in advance
Killboy Posted March 29, 2008 Author Posted March 29, 2008 Nevermind, I think I figured it out:QWORD structure actually looks like this:Lo-Value | Hi-Valuejust like ULONGLONG for C++
