serialize using stream. - binary

[magicast]

hi~ I apologize being not good at English. I wanna serialize my own data for network/file/etc... I thought that stream of c++ standard library is suitable. but, there's no facilities exactly for my use. 1. I wanna store stream data into memory.(not file) 2. insertion and extraction must operate in binary mode. // example of usage // proc A omystream ms; // mystream is that I wanted.. int n = 1; short s = 2; ms << n << s; // or ms << int_b(n) << short_b(s); // int_b(), short_b() is custom manipulators ::send(ms.buf(),...); // send to network // proc B BYTE buf[4096]; ::revc(buf,...); // receive from network imystream ms(buf, dwSizeReceived); // dwSizeReceived = 6 int n; short s; ms >> n >> s; // n = 1, s = 2 // or ms >> int_b(n) >> short_b(s); // result data occupy 6 bytes memory. (4 for n(int), 2 for s(short)) send and receive 6 byte of memory. memory layout: 00 00 00 01 00 02 // 6 byte not "000000010002" // 12 byte this mean not string but binary. how can I achieve it? derive strstream or stream? derive stream_buf? I need your advice. :) thanks in advance.

What you are looking for is ::CreateStreamOnHGlobal. You might consider SAFEARRAY(BYTE) as well (instead of).

The simplest way would be to deliminate all the data. In the case of streams, it would be easiest to use spaces, as the stream's default behaviour is to skip them.

ostringstream out;

int n = 1;
short s = 2;

out << n << ' ' << s;

// send the string over the network ( out.str () )

istringstream in ( out.str () );

n = s = 0;

in >> n >> s;

cout << "n = " << n << ", s = " << s << endl;
