Return values

[Francois Guimond <fguimond@xxxxxxxxxx>]

Thanks John for the quick answer about message hooks.

I use S-Lang to manipulate hardware registers.
I have intrinsics functions to do this.
I need to return a 32 bit value for the read command (idealy 64, but i can
handle 2*32)
Is it possible to use double reference to modify input variables
(**SLANG_ULONG_TYPE) or I have to push the result on the stack?

Thanks for the answer!
