Hello everyone! I am using Perl to embed it in C application, I need to have an ability to interrupt Perl function which have been invoked with `call_pv`. As function is invoked, it is blocking thread where it is running.
So, I see the only way to interrupt this blocking thread - via killing this thread with native "thread kill" functionality. But killing this thread results on program crash( (F)atal error -- Can't undef active subroutine during global destruction) and this can't be handled with exceptions or via other way. I am looking for correct way of handling the interruption of running perl function in C. So, is there any appropriate way to do this?
