Hi Josef.
IANAE, (I am not an expert) but if you say that the main thread returns
immediately and waiting in a loop for the lib, then you already have one
thread inside Perl. So the background threads shouldn't call into your
perl interpreter.
If I understand correctly, I have two options then:
1. _not_ let the main thread return back from the XS. That is, I
move the sleep(0) from the perl script into the init() function.
Would that break anything withhin perl?
For this one you need a real expert. It is possible to call into Perl
from an XS sub. but to call into Perl from other threads while it is
inside a XS call? I have no idea.
2. I need to create a second perl interpreter (or clone the first one).
Can somebody point me to example code how to do that?
That's actually no big deal. look at perldoc page perlembed, there are
examples.
