Detailed Description

Abstract base class for all the concrete implementation classes that provide different implementations for the ACE_Asynch_Read_Stream.

Member Function Documentation

virtual int ACE_Asynch_Read_Stream_Impl::read ( ACE_Message_Block message_block,
size_t  bytes_to_read,
const void *  act,
int  priority,
int  signal_number 
)
pure virtual

This starts off an asynchronous read. Upto bytes_to_read will be read and stored in the message_block.

Implemented in ACE_POSIX_Asynch_Read_File, ACE_Asynch_Read_File_Impl, and ACE_POSIX_Asynch_Read_Stream.

virtual int ACE_Asynch_Read_Stream_Impl::readv ( ACE_Message_Block message_block,
size_t  bytes_to_read,
const void *  act,
int  priority,
int  signal_number 
)
pure virtual

Same as above but with scatter support, through chaining of composite message blocks using the continuation field.

Implemented in ACE_Asynch_Read_File_Impl.
