Hi there I'm experiencing a strange compilation error that I cannot
resolve myself.
The following non-functionating triggers the error. I'm using VC2003
SP1. The error is due to the write() call.
template <class T > void sent( const T& object )
{
std::ostringstream archive_stream;
boost::archive::binary_oarchive archive( archive_stream );
archive & object;
std::string outbound_data = archive_stream.str();
// Format the header.
std::ostringstream header_stream;
header_stream << std::setw( 8 )
<< std::hex
<< outbound_data.size();
std::string outbound_header = header_stream.str();
// Write the serialized data to the socket. We use "gather-write" to send
// both the header and the data in a single write operation.
std::vectorboost::asio::const_buffer buffers;
buffers.push_back(boost::asio::buffer(outbound_header));
buffers.push_back(boost::asio::buffer(outbound_data));
boost::asio::write( socket, buffers );
}
This is the verbose error message:
