Abstract base class for all the concrete implementation classes that provide different implementations for the ACE_Asynch_Read_File::Result.

This class contains asbtract base classes for all the concrete implementation classes for the various asynchronous operations that are used with the Praoctor.

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