Code:

Structure STRUCTURE

stdcall MyCoolFunction, [Structure.member1], [Structure.member2]
...
proc MyCoolFunction value1,value2
  mov ecx,[value1]
  mov edx,[value2]
...

Or:

Code:

Structure STRUCTURE

stdcall MyCoolFunction Structure
...
proc MyCoolFunction pointerToStructure
  mov eax,[pointerToStructure]
  mov ecx,[eax+STRUCTURE.member1]
  mov edx,[eax+STRUCTURE.member2]
...
