Abstract base class for all the concrete implementation classes that provide different implementations for the ACE_Asynch_Read_File::Result.
class ACE_Asynch_Read_File_Impl : public virtual ACE_Asynch_Read_Stream_Impl {
public:virtual ~ACE_Asynch_Read_File_Impl (void);virtual 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 int read ( ACE_Message_Block &message_block, u_long bytes_to_read, const void *act, int priority, int signal_number ) = 0;protected:ACE_Asynch_Read_File_Impl (void);};
This class contains asbtract base classes for all the concrete implementation classes for the various asynchronous operations that are used with the Praoctor.

virtual int read (
ACE_Message_Block &message_block,
u_long bytes_to_read,
u_long offset,
u_long offset_high,

) = 0;
bytes_to_read will
be read and stored in the message_block. The read will start
at offset from the beginning of the file.

bytes_to_read will
be read and stored in the message_block.
