what I want. However, somewhere there is a fault. Editing a random

telling me where the application crashed (which I already knew) I did
not get anything useful out of it. To minimize my own potential errors I
have here below the example script from where I started (though I have
removed some unnecessary stuff) and commented out the 'long *outvl' and
'*outvl = -1'. Uncommenting, compile, and run this and I get a
segmentation fault.
You never allocate memory for the pointer long *outvl after you create
it, but then try to point to a value. You need to use malloc() to
initialize the memory for that pointer before you can use it.
