Dear Derek,

thank you very much for your information. Andreas, could you fix that
line of code. Seems to be very strange.

Please send us the modification for VxWorks. We will include these
modifications. It would be very good for us, if the prototype also
runs under VxWorks.

Best regards and thank you again
Michael

We have succesfully ported siemens SCTP to vxWorks, but we made a number of
changes and ran across a few issues.

A guy on our team who did most of the porting is coming up with a list of
changes we made, plus a few issues we came up with if anybody is interested
in them.

Here is one issue that has more to do with the compiler than with the OS.
We are running all this on a G4 processor (PowerPC 7410), so we use the GNU
C compiler for PowerPC.

Here is a snippet of code:


if ((ExitCode = DLL_GetCurrentRecord(rbuf->frag_list, &frag)) !=
DLL_NORMAL)
DLL_error_log(ERROR_MAJOR, ExitCode);
----> frag.stop_tsn = frag.stop_tsn++;
event_logiii(VVERBOSE,
"Updating last fragment frag.start==%u, frag.stop==%u,
tsn=%u",
frag.start_tsn, frag.stop_tsn, ch_tsn);
ExitCode = DLL_UpdateCurrentRecord(rbuf->frag_list, &frag);
rbuf->new_chunk_received = TRUE;
return FALSE;

The line I marked above (from recvctrl.c, line 415) does different things
under Solaris GNU C compiler than it does under PowerPC GNU C compiler.
Under Solaris, it increments frag.stop_tsn. Under PowerPC it DOESNT
increment frag.stop_tsn.

I think the line is a bug in either case, but it just so happens to work
under Solaris.
