Title: passing an array of structures by value to a prototype
Post by: ToutEnMasm on October 07, 2010, 01:59:34 PM

I try to find a syntax like this one:
AppelMoi PROTO :D3DVERTEXELEMENT9[3] ???
The only soluce i found is below.

Quote
D3DVERTEXELEMENT9   STRUCT
   Stream WORD ? ; Stream index
   offset1 WORD ? ; Offset in the stream in bytes
   type1 BYTE ? ; Data type
   Method BYTE ? ; Processing method
   Usage BYTE ? ; Semantics
   UsageIndex BYTE ? ; Semantic index
D3DVERTEXELEMENT9      ENDS
AGROUPE STRUCT
   regroupe D3DVERTEXELEMENT9 3 dup (<>)
AGROUPE ENDS
   ;machin
   AppelMoi PROTO :AGROUPE ; ----> D3DVERTEXELEMENT9[3] ?
   .data
   memostack dd 0
   regroupe AGROUPE <>
   .code

   start:
   mov eax,esp
   mov memostack,eax
   invoke AppelMoi,regroupe

   invoke ExitProcess,0
   ;------- proc içi ------------

;################################################################
AppelMoi PROC untruc:AGROUPE
      mov eax,memostack
      lea edx,untruc
      sub eax,edx         ;3 * 8 = 18h
      mov ecx,sizeof D3DVERTEXELEMENT9 ; 8
      mov eax,sizeof regroupe        ; 18h
FindeAppelMoi:
ret
AppelMoi endp

Assembles just fine:

AppelMoi PROTO :D3DVERTEXELEMENT9, :D3DVERTEXELEMENT9, :D3DVERTEXELEMENT9

Code Select

include \masm32\include\masm32rt.inc

D3DVERTEXELEMENT9   STRUCT
   Stream WORD ? ; Stream index
   offset1 WORD ? ; Offset in the stream in bytes
   type1 BYTE ? ; Data type
   Method BYTE ? ; Processing method
   Usage BYTE ? ; Semantics
   UsageIndex BYTE ? ; Semantic index
D3DVERTEXELEMENT9      ENDS
   ;machin
   AppelMoi PROTO :D3DVERTEXELEMENT9, :D3DVERTEXELEMENT9, :D3DVERTEXELEMENT9
   .data
   memostack dd 0
   d3a D3DVERTEXELEMENT9 <>
   d3b D3DVERTEXELEMENT9 <>
   d3c D3DVERTEXELEMENT9 <>
   .code

   start:
   mov eax,esp
   mov memostack,eax
   invoke AppelMoi, d3a, d3b, d3c
   
   invoke ExitProcess,0
   ;------- proc içi ------------
   
;################################################################
AppelMoi PROC  untrucA:D3DVERTEXELEMENT9, untrucB:D3DVERTEXELEMENT9, untrucC:D3DVERTEXELEMENT9
      mov eax,memostack
      lea edx,untrucA
      sub eax,edx         ;3 * 8 = 18h
      mov ecx,sizeof D3DVERTEXELEMENT9 ; 8
      mov eax, 3*sizeof untrucA
 FindeAppelMoi:
         ret
AppelMoi endp
end start
