This class is a factory for starting off asynchronous reads on a file.
class ACE_WIN32_Asynch_Read_File : public virtual ACE_Asynch_Read_File_Impl, public ACE_WIN32_Asynch_Read_Stream {
public:
ACE_WIN32_Asynch_Read_File (ACE_WIN32_Proactor *win32_proactor);
int read ( ACE_Message_Block &message_block, u_long bytes_to_read, u_long offset, u_long offset_high, const void *act, int priority, int signal_number = 0 );
virtual ~ACE_WIN32_Asynch_Read_File (void);
int open ( ACE_Handler &handler, ACE_HANDLE handle, const void *completion_key, ACE_Proactor *proactor );
int cancel (void);
ACE_Proactor* proactor (void) const;
private:
int read ( ACE_Message_Block &message_block, u_long bytes_to_read, const void *act, int priority, int signal_number = 0 );
};
These classes only works 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.
int open (
ACE_Handler &handler,
ACE_HANDLE handle,
const void *completion_key,
ACE_Proactor *proactor
);
handle
== ACE_INVALID_HANDLE),
ACE_Handler::handle
will be called on the handler
to get the
correct handle.
int cancel (void);
ACE_Proactor* proactor (void) const;
