[omniORB] Re: Getting client IP address in server + example interceptors

[Brecht Vermeulen]

so, now the cross platform version (thanks Duncan for pointing this out
!), with omni_thread class instead of pthread specific functions (this
was my first use of omnithread, so I hope it is fairly correct):

insert this in eg2_impl:

// For interceptors
#include <omniORB4/omniInterceptors.h>

// Thread specific data
#include <omnithread.h>
omni_thread::key_t key;

// Specifically for use of info in giop_s in
serverReceiveRequest_T::info_T
#include <giopStrand.h>
#include <giopStream.h>
#include <GIOP_S.h>

class clientaddress : public omni_thread::value_t {
public:
	clientaddress(const char * const client) {
		_client = new char [strlen(client)+1];
		strcpy(_client, client);
	};
	
	~clientaddress() { 
		cout << "Delete thread specific data :" << _client << endl;
		delete[] _client; };
	
	char *address() { return _client;};
private:
	char *_client;
};

CORBA::Boolean
testfunc(omni::omniInterceptors::serverReceiveRequest_T::info_T& info) {
	cout << "Operation name : " << info.giop_s.operation_name() << endl;
	cout << "Peer (client) address : " << ( (omni::giopStrand&)info.giop_s
).connection->peeraddress() << endl;
	cout << "My (server) address : " << ( (omni::giopStrand&)info.giop_s
).connection->myaddress() << endl;
	omni_thread::self()->set_value(key, new
clientaddress(((omni::giopStrand&)info.giop_s).connection->peeraddress()
));
	return true;
}


before poa_manager->activate:

key = omni_thread::allocate_key();
omniORB::getInterceptors()->serverReceiveRequest.add(&testfunc);


and in the IDL operation:
  cout << "echoString: client address : " << (
(clientaddress*)omni_thread::self()->get_value(key))->address() << endl;

Brecht
