[Swig-user] Multiple argument typemaps

[Bill S. <wf...@sa...>]

What is the proper way to define a set of typemaps for the following  
type of method:

     void insertMatrixEntries(int row, int length, double *values,  
int *indices);

The int "length" describes the size of both of the C-arrays "values"  
and "indices", so I want a python argument list like

     def insertMatrixEntries(self, row, values, indices):

where values and indices are python sequences (that will be converted  
in the typemap) and their lengths are required to be equal.  If I  
write a single input typemap for (int length, double *values, int  
*indices), then the resulting code expects a single python argument,  
not two.  If I split it up into two typemaps (int length, double  
*values) and (int *indices) then communication between the two  
typemaps becomes an issue.  I am familiar with how you define local  
variables, but the $argnum will be different between the two typemaps.

I have a lot of methods with this signature, so typemaps are  
definitely the way to go in this case.
