Is it possible to have structures in the proc macro?
EX: proc var1, var2, systime:SYSTEMTIME  |

You don't push the structure on stack, you only push the pointer to structure. And pointer is always DWORD.

Yeh, I know, but would it be too difficult to add this feature, it would make coding a bit easier.

no, IMO it would be stupid to add this feature, mainly because people will use it without knowing what they are doing.

Why would someone use this feature if they don't know what it is, or what it does? Anyways, using assembly for ANYTHING requires a good bit of programming skill to start with.

so what difference would it make to have ptrSomeStructure:STRUCTURE compared to this code?
Code: format PE GUI 4.0 entry start include '%fasminc%\win32ax.inc' struct Bleh asdasd rd 1 asdasd1 rd 1 dwTest rd 1 ends humm dd 69h bleh_struct Bleh proc TestProc ptrBleh:dword mov edx, [ptrBleh] lea ecx, [edx] mov eax, [ecx+Bleh.dwTest] ret endp start: mov ecx, bleh_struct lea eax, [ecx] push dword [humm] pop [eax+Bleh.dwTest] push bleh_struct call TestProc ;eax = 69h _________________ When We Ride On Our Enemies support reverse smileys |: |

It would push the whole structure on the stack and not just a pointer.

It's not the "proc" macro that pushes parameters on the stack.

okasvi,
Let me clarify something, the invoke macro would actually push the structure data on the stack. And the proc macro would actually define the stack pointers to the data. And you would access it just like you would a local structure. |
