Hello,

I want to establish a SMTP connection through a socket, then dialog with the
server using a stream. I thought I could to it like this:
//--------------------------------------------
#include <boost/iostreams/stream.hpp>
#include <boost/iostreams/device/file_descriptor.hpp>

using namespace std;
using namespace boost::iostreams;

...
int theSocket = socket(AF_INET,SOCK_STREAM,0);
connect(theSocket, ...);
        
file_descriptor fdDevice(theSocket);
stream_buffer<file_descriptor> fdstream(fdDevice);
iostream os(&fdstream);

string answer;
getline(os, answer);
cout << answer << endl;
os << "HELO xxxxx" << endl;
getline(os, answer);
cout << answer << endl;
os << "MAIL FROM: <xxx.xxx_at_xxx.xxx>" << endl;
getline(os, answer);
cout << answer << endl;
...
//--------------------------------------------
But nothing seems to be written nor readen to/from the socket except for the
first getline. What am I doing wrong here ?

Thanks in advance for any help.
