Member Function Documentation

read()

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_Asynch_Read_File_Impl, ACE_POSIX_Asynch_Read_File, and ACE_POSIX_Asynch_Read_Stream.

readv()

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.
