[Help-smalltalk] Correct way to throw exceptions/errors from C to ST

[Roland Plüss]

Another something that I could not really figure out using the
documentations. Let's say you have a CCallOut from ST to C. Inside this
C function something goes wrong, for example an invalid argument passed.
How do you properly raise an exception back to Smalltalk? I tried doing
something like this:

gst_eval_code( "SystemExceptions.InvalidArgument new signal" );

But this causes the VM to call abort since an exception happened outside
the bytecode. I assume you need to be more clever in this case. So what
is the correct way to throw these kinds of exceptions from inside a C
function?
