Naive pointer question ? [message #28944]

From my understanding, pointers are useful in C where you have the
option of passing by value or by reference, but in IDL it seems one
*always* passes by reference (insofar as any variable passed to a
function and then changed within that function is also changed in the
calling function).

So I was wondering, what is the benefit of explicitly using pointers
in IDL ?

Ciao.
