Access Write Violation When Accessing the Value of a Register in assembly x86 -

- 

compare proto, p1:dword, p2:dword .code compare proc p1:dword, p2:dword     mov eax, p1     mov edx, p2     mov eax, [eax] ;getting access violation here     mov edx, [edx] ; 1 here too, why?     sub eax, edx     ret compare endp main proc      local thesize:dword     mov thesize, 3     mov fill, 5     invoke compare, thesize, thesize      ret main endp

hey guys, curious why code isn't working? what's alternative way make work, i'm playing around registers , trying similar code when filling array, got stuck @ point.

thanks in advance!

not sure doing, since looks want dereference mem address, must use addr local vars get/pass address.

main proc      local thesize:dword     mov thesize, 3  ;    invoke compare, thesize, thesize ;    same as: ;    push    3 ;    push    3 ;    call    compare      ; want:     invoke compare, addr thesize, addr thesize ;    same as: ;    lea     eax, thesize ;    push    eax ;    push    eax ;    call    compare     ret main endp
