This starts off an asynchronous read. Upto bytes_to_read will be read and stored in the message_block. The read will start at offset from the beginning of the file.
Implemented in ACE_POSIX_Asynch_Read_File.

Same as above but with scatter support, through chaining of composite message blocks using the continuation field.
- Note:
- In win32 Each data block payload must be at least the size of a system memory page and must be aligned on a system memory page size boundary
