hook a VM termination. Right now, because the VM we have is process global, most extensions do not deallocate resources and leave them to Operating System's reaping userland processes. But in a future we plan to have multiple VMs to run simultaneously in a single process (MVM project). At that stage we can no longer rely on OSes and have to manage every resources to be reclaimed properly. So it is. For a forward-compatibility reason this API is introduced now, encouraging you to be as gentle as you can for your resources; that is, tidy up your room. * include/ruby/vm.h: ditto. * vm_core.h (rb_vm_struct): new field. * vm.c (vm_init2): initialize above new field. * eval.c (ruby_cleanup): trigger those hooks. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@30050 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* of registration, just like END {} block does. The difference is

|
* its timing to be triggered. ruby_vm_at_exit functions runs when a

|

* 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.
|
|
*
|
|
* @param[in] func the function to register.
