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_Stream, and ACE_POSIX_Asynch_Read_File.

) | [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.
