Hi,
I am trying to clone a socket from process to another, mostly for
having one process per client in a network server.
Some legacy stuff makes this the only design possible, so the threaded
approach is simply not feasible...
Anyway, when I'm trying to create a boost socket from a cloned WSA
socket I get an exception.
class boost::exception_detail::clone_impl<
struct boost::exception_detail::error_info_injector<
class boost::system::system_error
>
: The parameter is incorrect
This same happens for this example program, using boost 1.37
Does anyone have an idea why this does not work?
#ifndef _WIN32_WINNT
#define _WIN32_WINNT 0x0501
#endif
#define WIN32_LEAN_AND_MEAN
#define NOMINMAX

#pragma comment(lib, "ws2_32")
#include
namespace ip = boost::asio::ip;
int main_impl(int argc, char* argv[])
{
boost::asio::io_service ios;
ip::tcp::socket s(ios);
ip::tcp::acceptor a(ios, ip::tcp::endpoint(ip::tcp::v4(), 1777));
a.accept(s);
WSAPROTOCOL_INFO info;
if (WSADuplicateSocket(s.native(), GetCurrentProcessId(), &info))
{
std::cerr << "WSAError: " << WSAGetLastError() << std::endl;
return EXIT_FAILURE;
}
// pass info over a pipe to the client...
SOCKET copy(WSASocket(FROM_PROTOCOL_INFO, FROM_PROTOCOL_INFO
, FROM_PROTOCOL_INFO, &info, NULL, NULL));
ip::tcp::socket scopy(ios, ip::tcp::v4(), copy);
return EXIT_SUCCESS;
}
int main(int argc, char* argv[])
{
try
{
return main_impl(argc, argv);
}
catch(std::exception const& ex)
{
std::cerr << typeid(ex).name() << ":"
<< ex.what() << std::endl;
return EXIT_FAILURE;
}
}
