#include <ace/Dynamic.h>
class ACE_Dynamic
{
  public:
    ACE_Dynamic (void);
    ~ACE_Dynamic (void);
    void set (void);
    int is_dynamic (void);
    void reset (void);

## DESCRIPTION

This class holds the pointer in a thread-safe manner between the call to operator new and the call to the constructor.

## Initialization and termination method.

```
ACE_Dynamic (void);
```

Constructor.

```
~ACE_Dynamic (void);
```

Destructor.

```
