NAME

ACE_Handler - This base class defines the interface for receiving the results of asynchronous operations.

SYNOPSIS

class ACE_Handler { public: ACE_Handler (void); ACE_Handler (ACE_Proactor *p); virtual ~ACE_Handler (void); virtual void handle_read_stream ( const ACE_Asynch_Read_Stream::Result &result ); virtual void handle_write_stream ( const ACE_Asynch_Write_Stream::Result &result ); virtual void handle_read_file ( const ACE_Asynch_Read_File::Result &result ); virtual void handle_write_file ( const ACE_Asynch_Write_File::Result &result ); virtual void handle_accept ( const ACE_Asynch_Accept::Result &result ); virtual void handle_transmit_file ( const ACE_Asynch_Transmit_File::Result &result ); virtual void handle_time_out ( const ACE_Time_Value &tv, const void *act = 0 ); virtual void handle_wakeup (void); ACE_Proactor *proactor (void); void proactor (ACE_Proactor *p); virtual ACE_HANDLE handle (void) const; protected: ACE_Proactor *proactor_; };

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.
