What pthread_kill is doing?

[murasesyuka]

there is one question.

what mean under the code?

pthread_kill(context->thread, 0);

if checking thread_id valid or thread exist, I think it need return value. for example

if (pthread_kill(context->thread, 0) == ESRCH){ /*  Not a valid thread  */ }

do you mean pthread_kill in mrb_thread_kill ?

[murasesyuka]

Both in mrb_thread_kill () and in mrb_thread_context_free ().

[mattn]

This is complementary call for terminating thread.
