Hi guys,

(another question from a former MASM user Smile

)

Is it possible in FASM to declare the type for an "extrn" variable?

Code:

extrn  p1:sMyStruct


mov  eax, [p1.field_in_MyStruct]

It seems that FASM doesn't like the "extrn p1:sMyStruct" Sad

Not sure if there is a workaround for it.

Thanks!

alorent,

FASM doesn't like p1.field_in_MyStruct too, unless told to. Wink

Use something like

Code:

extrn "p1" as extrn_p1
virtual at extrn_p1
  p1 sMyStruct
end virtual

Thanks baldr!

You are very good Wink

I was wondering if there is any way to overload the "extrn" macro so it contain all your above code.

I guess that it doesn't look nice to declare 10 extern symbols and we have to include all your above code for each extrn Wink

Anyway, thanks again!
