NAME

ACE_Asynch_Read_File_Impl -

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

SYNOPSIS

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); };

DESCRIPTION

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