Yeah that sounds like it could screw things up. :)

While we are on the subject of pointers to pointers, and copies of references, what would one use this level of indirection for?

For example-

VFP:

someFunc(@oObj)

C/C++:

int someFunc(void **ppint);

And I have seen it (in COM literature for example) cast like:

x = someFunc((void**) *&pvar);

What is the reason for this?

TIA,
Bill
