Protocol Buffers What is it?
Protocol Buffers are a way of encoding structured data in an efficient yet extensible format. Google uses Protocol Buffers for almost all of its internal RPC protocols and file formats.

Quick Example
You write a .proto file like this:
message Person { required int32 id = 1; required string name = 2; optional string email = 3; }
Then you compile it with protoc, the protocol buffer compiler, to produce code in C++, Java, or Python.
Then, if you are using C++, you use that code like this:
Person person; person.set_id(123); person.set_name("Bob"); person.set_email("bob@example.com"); fstream out("person.pb", ios::out | ios::binary | ios::trunc); person.SerializeToOstream(&out); out.close();
Or like this:
Person person; fstream in("person.pb", ios::in | ios::binary); if (!person.ParseFromIstream(&in)) { cerr << "Failed to parse person.pb." << endl; exit(1); } cout << "ID: " << person.id() << endl; cout << "name: " << person.name() << endl; if (person.has_email()) { cout << "e-mail: " << person.email() << endl;
}
For a more complete example, see the tutorials.
sample command:
protoc.exe -I=.\ --cpp_out=.\ unittest.proto
