Hold Object Manager cleanup (exit) information.

## NAME

ACE\_OS\_Exit\_Info -  Hold Object Manager cleanup (exit) information.

## SYNOPSIS

```
#include <ace/OS.h>
class ACE_OS_Exit_Info
{
  public:
    ACE_OS_Exit_Info (void);
    ~ACE_OS_Exit_Info (void);
    int at_exit_i (
        void *object,
        ACE_CLEANUP_FUNC cleanup_hook,
        void *param
        );
    int find (void *object);
    void call_hooks ();
  private:
    ACE_Cleanup_Info_Node *registered_objects_;
};
```

## DESCRIPTION

For internal use by the ACE library, only.

## PUBLIC MEMBERS

```
ACE_OS_Exit_Info (void);
```

Default constructor.

```
~ACE_OS_Exit_Info (void);
```

Destructor.

```
int at_exit_i (
    void *object,
    ACE_CLEANUP_FUNC cleanup_hook,
    void *param
    );
```

Use to register a cleanup hook.

```
int find (void *object);
```

Look for a registered cleanup hook object.  Returns 1 if already registered, 0 if not.

```
void call_hooks ();
```

Call all registered cleanup hooks, in reverse order of registration.

```

Keeps track of all registered objects.  The last node is only used to terminate the list (it doesn't contain a valid ACE\_Cleanup\_Info).

## The ACE\_Sched\_Priority type should be used for platform-

independent thread and process priorities, by convention. int should be used for OS-specific priorities.

## typedef for the \_stat data structure

## Giving unique ACE scoped names for some important

RTSignal-Related constants. Becuase sometimes, different platforms use different names for these constants.
