UDP sockkets in BlackBox CP

Postby dmaksimiuk » Sat Oct 17, 2015 6:29 pm

Hi all,
Is there any (fast, easy, and simple) way to get UDP sockets working with the framework? The CommTCP supports only ... TPC right?
There is Ta_ subsystem developed by Dmitry V.Dagaev but at this stage it would be an overkill for my application.
Any suggestions ?

Cheers,
Darek

Yes, Peter Kushnir made this:
https://bitbucket.org/oberoncore/ypk/sr ... at=default

Look at the CommUDP.odc. It is the alternative for CommTCP.

All the ypk subsystem may be useful :)

Hi Ivan,
I got the ypk software from the repository (I could not find the WinHdrs subsystem). When I tried to compiler the ypkCommUDP module I got an error:
Code: Select all
PROCEDURE NameToAdr (IN peername: ARRAY OF CHAR; VAR inaddr: WinNet.in_addr; OUT ok: BOOLEAN);
      VAR hostentry: WinNet.Ptrhostent; shortPName: ARRAY 64 OF SHORTCHAR;
   BEGIN
      shortPName := SHORT(peername$);
      IF IsIPAddress(peername) THEN
         inaddr.S_un.S_addr := WinNet.inet_addr(shortPName);
         ok := (peername$ = '255.255.255.255') OR (inaddr.S_un.S_addr # WinNet.INADDR_NONE);
                       (* pk,  потому что: An Internet address with a dot notation value of 255.255.255.255 or its
                           equivalent in a different base format causes the inet_addr subroutine to return an unsigned integer
                           value of 4294967295. This value is identical to the unsigned representation of the error value.
                           Otherwise, the inet_addr subroutine considers 255.255.255.255 a valid Internet address.
                        *)
         ASSERT(ok);
      ELSE
         hostentry := WinNet.gethostbyname(shortPName);
         ok := hostentry # NIL;
         IF ok THEN
            inaddr := hostentry.h_addr_list^[0]^[0]  [b]  <-- Error : incompatible assignment
         ELSE
            Error("gethostbyname()", WinNet.WSAGetLastError())
         END
      END
   END NameToAdr;


I seems that Peter's version of the software is not compatible with the BBox I am using (1.7-RC6 built number 44).

Cheers,
Darek

Look at Transparent Architecture component.
Transparent Architecture is a library for distributed systems development. It is designed as cross-platform, tested for Windows and Linux.

TA implements non-blocking I/O with a set of transport protocols supported: multicast, UDP, TCP, ICMP, Shared Memory, Unix Domain Sockets, Unix Message Queue.

TA is designed to cover a wide range of communication: Real-Time, LAN Ethernet and WAN SOAP. It can be a pilot of unified substituting technology for CORBA, COM and DDS.

TA is distributed in C and Oberon versions compatible with each other.

It is not easy to compile this subsystem :( there is some instruction how to build superset of ypk called bb.open
The WinHdrs was transformed and now it is placed here:
https://bitbucket.org/oberoncore/interf ... efault.zip

For sure, he was using he's own version. But it should be compatible with 1.6.
Now I recommend you to use Center version. CommUDP is compatible with Center BB 1.7 Alpha 1.

UPD:
I asked, Peter Kushnir, unfortunately he have no time to support ypk anymore for new versions of BlackBox.

Hi Ivan,
where I can find the center version of the CommUDP ?

I mean Center version of BlackBox!
http://blackboxframework.org/lastdev/zip.php
Peter's CommUDP is compatible with it.

UPD: ypkCommUDP is independent from ypk, you can use it separately as a single module like CommTCP.
