boost::asio::buffer: Getting the buffer size and preventing buffer overflow?

Question

I have the two following functions for sending and receiving packets.

void send(std::string protocol)
{
    char *request=new char[protocol.size()+1];
    re         


        

Answer 1

I think your question is confusing, but this might help:

void receive() {
  enum { max_length = 1024 };
  char reply[max_length];
  size_t reply_length;
  std::cout << "Reply is: ";
  while ( (reply_length = ba::read(s, basio::buffer(reply, max_length))) > 0) {
    std::cout.write(reply, reply_length);
  }
  std::cout << "\n";
}
