Re: Sockets problem

[Ron@xxxxxxxxxx]

Scott,

I don't know if you saw my original post, listing the apis we are calling
so I'll post them here again. This code works well for other socket
connections, but this is the first time we've connected with a server that
is handing off the connection so I wasn't sure if there was a piece I was
missing.  I'm glad to hear you say that the handoff is invisible to the
client, because thats the way i understood it to be also. I just noticed we
are doing a WRITE instead of a SEND (but our programmer says she's tried it
both ways and neither works).

Heres what we run:

 Create a socket descriptor for the server process to bind.
                  EVAL      SrvrSktId = Socket(AF_INET
                                                  :SOCK_STREAM
                                                  :0)

** Set socket descriptor to be reuseable.
      c             EVAL      RtnCd = SetSockOpt(SrvrSktId
      C                                               :SOL_SOCKET
      C                                               :SOL_REUSEADDR
      C                                               :%ADDR(On)
      C                                               :%SIZE(On))


  *   Connect to the server
        C                   Eval      RtnCd = Connect(SrvrSktId:
        C                                            %Addr(ServerAddr) :
        C                                            %Size(ServerAddr)  )
        C                   EVAL      svaddrlen = %SIZE(serveraddr)



       C                   IF        NOT *IN68
       C                   EVAL      RtnCd2 = Write(SrvrSktId
       C                                           :%ADD



Here's what the vendor told us to do:

Looking at what should be done at CPU's side, the logic should be:

// Create an unconnected socket for TCP/IP
m_Sockfd = ::socket(AF_INET, SOCK_STREAM, 0);

// Connect to serv_addr (207.230.238.11, 5550) and
// set m_Sockfd to some unique value (e.g., 34567)
connect(m_Sockfd, (struct sockaddr*)&serv_addr, sizeof(serv_addr));

// Send messages to 34567
send(m_Sockfd, outBuffer, ::strlen(outBuffer), 0)


Presumably, they'll be using the above calls (BSD sockets API).
