Function Documentation

void ruby_vm_at_exit ( void(*)(ruby_vm_t *)  func)

ruby_vm_at_exit registers a function _func_ to be invoked when a VM passed away.

Functions registered this way runs in reverse order of registration, just like END {} block does. The difference is its timing to be triggered. ruby_vm_at_exit functions runs when a VM _passed_ _away_, while END {} blocks runs just _before_ a VM _is_ _passing_ _away_.

You cannot register a function to another VM than where you are in. So where to register is intuitive, omitted. OTOH the argument _func_ cannot know which VM it is in because at the time of invocation, the VM has already died and there is no execution context. The VM itself is passed as the first argument to it.

Parameters:
[in]functhe function to register.
