/**
* @class ACE_MEM_Stream
*
* @brief Defines the methods in the ACE_MEM_Stream abstraction.
*
* This adds additional wrapper methods atop the ACE_MEM_IO
* class. Notice that ACE_MEM_Stream can only send messages no bigger
* than the underlying MMAP file size minus sizeof (ACE_MEM_SAP_Node).
* The size of the MMAP file is default to ACE_MEM_STREAM_MIN_BUFFER.
* (Define above in this file, to 4096 bytes.)
* If you need to increase the size of allowable message
* ACE_MEM_Stream can handle, you can set it to either
* @c ACE_MEM_Acceptor::malloc_options(). minimal_bytes_
* @c ACE_MEM_Acceptor::init_buffer_size (size_t size);
* before establishing a connection.
