[Scilab-users] Interfacing to third party DLLs

[antoine.elias at scilab-enterprises.com]

Hello James,

inputs arguments of your interface must be pointers, Scilab manage data 
as matrix ( arrays in C )
So a scalar variable `A` become a `double A[1];`

prototype must be like this :
void Add(double* a, double* b, double* c);


I made some changes is yours files, take a look, I hope that can help 
you.

Antoine
