[erlang-questions] [Q] erlang:check_process_code/2

[Ladislav Lenart]

Hello,

I think I run into trouble with code purge/delete machinery. To solve
this puzzle, I need to understand how erlang:check_process_code/2
works. Could anyone please tell me under which circumstances this
function returns true? I know that it is "when a process is executing
old code" but what does that really mean (for example, what if the
process references a Fun from that module,...)?

Thanks,

Ladislav Lenart
