Unfortunately I don't know the size of the event, so that won't work.
If you like to return it via the door_return(char *data_ptr,
you could first copy it to an autromatic variable and then
free the original. And you could just use alloca() to get
the data space.
Excellent. I'll give this a try.

How much data is it? Can you copy it on the stack, free it and

It should be enough to fit on the stack, so using alloca() seems to
be the best solution.
Thanks!
