How do you use a structure with a pointer in fasm? I have allocated memory and want to fill it with a structure.
;
; ebp points to allocated memory
; we have a structure called struc with
{
.name rb 1
.token rb 1
}
; in nasm you would code:
mov [ebp+struc.name],byte value
;
I've tried: mov [ebp.name],value
mov [ebp+ .name],value

struc in fasm are an special case of macros actually so they not provide an actual type definition, yet, there is a well known workaround for it:
Code:
struc Point{
  .x dd ?
  .y dd ?
}
;; Workaround
virtual at 0
  Point Point
end virtual

; Now you can use the struc as an offset
mov [ebp+Point.y], 7
