string.size is not a defined symbol for struc, however if you do:
Code: str2 string 'some',0x0A,'text' then actually the symbol str2.size is defined: Code: mov dword [str2.size], str2-str0-5 |

str2 is actually an rb, so that doesn't work.
I know i've done something like this before when doing windows programming, but for some reason i can't get it to work anymore. I can even find posts here where suggestions like this are made, so i'm guessing it's something special one of the windows includes add, but i can't find which include it is... |

Well you can do string.size with struct:
Code: struct string
size dd ?
; not sure how to handle this bit though...

I could've sworn that struc itself was rewritten along with struct. Oh well, point made... I'll either have to write a wrapper struc to rewrite struct or support it in my struc. Thanks for your help.

Related problems, but not quite the same one. My main issue is that I have to do this:
Code: meow.size = 0 meow.text = 4 struc meow param { .size dd 0 forward .text db param } mov eax, [eax+meow.size] instead of: Code: struc meow param { .size dd 0 forward .text db param } mov eax, [eax+meow.size] because otherwise the code won't work. I could've sworn i was able to do the second code when i did windows programming, but perhaps i was wrong. |

struc doesn't DECLARE anything, it just DEFINES a structure.
Code: struc meow param { .size dd 0 forward .text db param } declared meow 4 mov eax, [eax+declared.size] 
(just like a macro) _________________ Previously known as The_Grey_Beast |

Indeed, i just thought that since i was able to do it (perhaps i was using struct somehow before) before, it was just a fancy feature of a structure.

from tha fasm manual, i read that:
Code: struct point x,y { dd x,y } p1 point 1,2 mov eax,[p1.x] mov ebx,[p1.y] struct is just an addressing method you can write a macro that use the structure. |
