[Quickfix-developers] Reading FIX message from Exchange/Broker server

[Ming C. <che...@ho...>]

Hi,

void SocketConnection::readFromSocket()
EXCEPT ( SocketRecvFailed )
{
  ssize_t size = socket_recv( m_socket, m_buffer, sizeof(m_buffer) );
  if( size <= 0 ) throw SocketRecvFailed( size );
  m_parser.addToStream( m_buffer, size );
}

ssize_t socket_recv(socket_handle s, char* buf, size_t length )
{
  return recv( s, buf, length, 0 );
}

Question:


  *   How to make sure FIX messages are always < BUFSIZ (8192 on developer's linux for example)? Say a message with many groups and some repeatingNo could be quite big?
  *   (Here I am not sure but like to learn) that recv can always read a complete message?

Thanks.
Ming
