Question regarding the use of defpascal:
Are there any guidelines for what you can/cannot do within a defpascal function
or within a function directly called from there? I'm thinking of potential
problems with moving memory, interrupting the current MCL process, etc.. I
don't want to go around rearranging vast amounts of memory without the
"correct" process knowing about it.
I know that some callbacks can occur during interrupt time, so that leads to
another question: What is the proper way to write MCL code to handle those
callbacks? Just queue up a handler form (via eval-enqueue) as fast as
possible? Should I even attempt to handle those types of callbacks in Lisp?
Any ideas would be appreciated!
