how to transfer object using socket (tcp/ip)
 

helo,
if i wan to develping socket application using c++on linux.
if i want to transfer whole object then how can i transfer object from server to client using socket(tcp/ip) protocol
Regards,

If it's between machines with the same endianness, you can just trasmit it as a block of bytes. If not, or if you simply want a more portable solution, you can serialize the structure, and then send the bytestream out. Take your pic; it depends on your needs.

Boost.Serialization is very comprehensive library which could be helpful.

what is serialization and how i use it
 

helo u say that i want to serialize the structure or object.
can u tell me what exactly is serialization and how i implement serialization

Serialization, in this sense, is the process of taking a chunk of data and coverting it to a sequence of bytes for some kind of operation (generally writing to disk or sending across a network connection). In some contexts, the disk write/network transmission is subsumed in the term 'serialization'.

One of the benefits of serialization is it converts internal representations of data to a series of bytes, and thus the byte order of the CPU doesn't matter. Say you transmit a 32-bit int across a network connection, and the sending computer is, say, an Intel x86-based machine. The x86 architecture is 'little endian', meaning that multi-byte values are ordered in memory with the least significant byte first. In other words, the value 0xAABBCCDD would be four bytes, in this order: 0xDD, 0xCC, 0xBB, and 0xAA. The receiving computer, on the other hand, might be a big-endian machine, expecting the bytes like so: 0xAA, 0xBB, 0xCC, and 0xDD. Hell, maybe the receiving machine uses 64-bit ints. Either way, you have a problem.

Another benefit is that many functions for writing to disk or communicating across a network expect a buffer of bytes to work with. Serialization gives you this buffer of bytes.
