How to access external global variables from masm?

[a_h]

Hi!

Currently I've some masm-assembly as .asm file that is part of a Visualc++6-project. In the .cpp file I declare global variables N, B of type unsigned int that I want to access.
---------------------------------
.686
.model flat, stdcall
option casemap :none

.code

Extrn _B:DWORD
Extrn _N:DWORD
...
--------------------------------
doesn't link. How can I access them?

Thanks for helping me out!

Cheers, Hannes

Hello,
The library must be link with the source,includelib .....
The source of the library must declare the external like that
          EXTERNDEF Copier :PROTO  :DWORD,:DWORD
          EXTERNDEF EtatMemoirePile :MEMORY_BASIC_INFORMATION
          EXTERNDEF PoriginePile:DWORD      
This externals can be use only by the library,to use it in your source
                PUBLIC  PoriginePile  ;for example
I have no sample of externdef with c,perhaps declaring the externdef in the include of the library is enough.

Merci beaucoup!

Unfortunately I don't understand your reply...I tried Extern _BitsLeft:dword (and without the underscore), but it simply issues the unresolved error.

Any ideas what I can try?
