Has anybody encountered a return code of 504 from DosRead?
I'm using it on named pipes for interprocess communication on the same
It usually fails just after doing a DosWrite which returns 0, but the
receiver on the other end of the pipe gets nothing.
This happens after about a week after several thousands such
transactions (DosWrite a structure of few hundred bytes, then DosRead
an unsigned long response). Restarting applications doesn't help, the
situation would occur sooner. I have to reboot to get another week of
(I cannot reproduce this with a traffic generator)
Thank you for any insight...
