ACE_Asynch_Operation(3)

NAME

ACE_Asynch_Operation -

This is an interface base class for all asynch operations. The resposiblility of this class is to forward all methods to its delegation/implementation class, e.g., ACE_WIN32_Asynch_Operation or ACE_POSIX_Asynch_Operation.

SYNOPSIS

class ACE_Asynch_Operation
{
  public:
    int open (
        ACE_Handler &handler,
        ACE_HANDLE handle,
        const void *completion_key,
        ACE_Proactor *proactor
        );
    int cancel (void);
    ACE_Proactor* proactor (void) const;
    virtual ~ACE_Asynch_Operation (void);
  protected:
    ACE_Asynch_Operation (void);
    ACE_Asynch_Operation_Impl *implementation (void) const;
    void implementation (ACE_Asynch_Operation_Impl *implementation);
    ACE_Proactor *get_proactor (
        ACE_Proactor *user_proactor,
        ACE_Handler &handler
        ) const;
    ACE_Asynch_Operation_Impl *implementation_;
};

DESCRIPTION

This works on Win32 (#if defined (ACE_WIN32) && !defined (ACE_HAS_WINCE)) platforms and on POSIX4 platforms with aio_* routines (#if defined (ACE_HAS_AIO_CALLS))

On Win32 platforms, the implementation of ACE_Asynch_Transmit_File and ACE_Asynch_Accept are only supported if ACE_HAS_WINSOCK2 is defined or you are on WinNT 4.0 or higher.

Access methods.

ACE_Proactor* proactor (void) const;

virtual ~ACE_Asynch_Operation (void);
