# ACE\_Thread\_Exit(3)

Keep exit information for a Thread in thread specific storage. so that the thread-specific exit hooks will get called no matter how the thread exits (e.g., via ACE\_Thread::exit, C++ or Win32 exception, "falling off the end" of the thread entry point function, etc.).

## NAME

ACE\_Thread\_Exit -  Keep exit information for a Thread in thread specific storage. so that the thread-specific exit hooks will get called no matter how the thread exits (e.g., via ACE\_Thread::exit, C++ or Win32 exception, "falling off the end" of the thread entry point function, etc.).

## SYNOPSIS

```
#include <ace/OS.h>
class ACE_Thread_Exit
{
  public:
    ACE_Thread_Exit (void);
    void thr_mgr (ACE_Thread_Manager *tm);
    void *status (void *s);
    void *status (void);
    ~ACE_Thread_Exit (void);
    static ACE_Thread_Exit *instance (void);
    static void cleanup (void *instance, void *);
  private:
    void *status_;
    ACE_Thread_Control thread_control_;
};
```

## DESCRIPTION

This clever little helper class is stored in thread-specific storage using the ACE\_TSS wrapper.  When a thread exits the ACE\_TSS::cleanup function deletes this object, thereby closing it down gracefully.

## PUBLIC MEMBERS

```
ACE_Thread_Exit (void);
```

Capture the Thread that will be cleaned up automatically.

```
void thr_mgr (ACE_Thread_Manager *tm);
```

Set the ACE\_Thread\_Manager.

```
void *status (void *s);
```

Set the exit status.

```
void *status (void);
```

Get the exit status.

```
~ACE_Thread_Exit (void);
```

Destructor calls the thread-specific exit hooks when a thread exits.

```
static ACE_Thread_Exit *instance (void);
```

Singleton access point.

```
static void cleanup (void *instance, void *);
```

Cleanup method, used by the ACE\_Object\_Manager to destroy the singleton.

## PRIVATE MEMBERS

```
void *status_;
```

Exit status...

```
ACE_Thread_Control thread_control_;
```

Automatically add/remove the thread from the ACE\_Thread\_Manager.
