fast and safe comparison of variables in foreign code?

[Erick Alphonse]

Hello,

I want to test equality and inequality of variables in foreign code 
(C++) but I would like to avoid the overhead of calling Blt_Term_Eq and 
Blt_Term_Neq (they are defined as functions, not as macros) and use == 
and != operators instead.

Does someone know if it is a safe way to do comparison of variables? I 
guess it depends on the way the interface passes the variable arguments?

Thanks in advance for your help,
Regards,
Erick.
