This code is to deal with the issue for pointer-pointer's
In particular for factory methods.
for example take the following code segment:
struct iMath; // some structure
int Create_Math(iMath** pptr); // its factory (assume it mallocs)
to use it you might have the following C code:
iMath* ptr;
int ok;
ok=Create_Math(&ptr);
// do things with ptr
//...
free(ptr);
With the following SWIG code
%apply SWIGTYPE** OUTPUT{iMath **pptr };
You can get natural wrappering in Lua as follows:
ok,ptr=Create_Math() -- ptr is a iMath* which is returned with the int
ptr=nil -- the iMath* will be GC'ed as normal
