[Swig-user] pass data between typemap

[Burlen L. <bur...@gm...>]

Hi, I'm trying to pass data via a local variable between two type maps 
that are always in a certain order. the argument for the typemap that 
passes the data is always directly preceding the argument for typemap 
that receives the data. Also there's only aver one such pair of 
arguments in any function. I'm having a problem in that the position of 
the first of this pair of arguments varies, and thus the name of the 
local variable changes (ie local1, local2, etc).

How in swig can I say $argnum-1 ??
Or could I disable the appending of the $argnum to the local variable 
name ??


typemap (in) (T1) (int local) {
    local = ....
    $1 = ...
}

typemap (in) (T2) {
   foo(local*$argnum-1*)
   $1 = ...
}

I want these to apply to the following c++ functions:

int blah(T1 v1, T2 v2);
int blas(int a, T1 v1, T2 v2);
