# ACE\_POSIX\_SIG\_Asynch\_Operation(3)

This class implements ACE\_Asynch\_Operation for Real-Time Signal (sigtimedwait) based implementation of Proactor.

## NAME

ACE\_POSIX\_SIG\_Asynch\_Operation -

This class implements ACE\_Asynch\_Operation for Real-Time Signal (sigtimedwait) based implementation of Proactor.

## SYNOPSIS

```
class ACE_POSIX_SIG_Asynch_Operation :
  public virtual ACE_POSIX_Asynch_Operation
{
  public:
    ACE_POSIX_SIG_Proactor *posix_proactor (void) const;
  protected:
    ACE_POSIX_SIG_Asynch_Operation (
        ACE_POSIX_SIG_Proactor *posix_sig_proactor
        );
    virtual ~ACE_POSIX_SIG_Asynch_Operation (void);
    ACE_POSIX_SIG_Proactor *posix_sig_proactor_;
};
```

## DESCRIPTION

The implementation classes for POSIX implementation of Asynch Operations are defined here in this file.

## PUBLIC MEMBERS

```
ACE_POSIX_SIG_Proactor *posix_proactor (void) const;
```

Return the  underlying Proactor implemetation.

## PROTECTED MEMBERS

```
ACE_POSIX_SIG_Asynch_Operation (
    ACE_POSIX_SIG_Proactor *posix_sig_proactor
    );
```

Contructor.

```
virtual ~ACE_POSIX_SIG_Asynch_Operation (void);
```

Destructor.

```
ACE_POSIX_SIG_Proactor *posix_sig_proactor_;
```

It is easy to get this specific implementation proactor here, since it is the one that creates the correct POSIX\_Asynch\_\* objects. We can use this to get to the implementation proactor directly.
