I wrote a small test program using normal Queue calls
then ran it both on my development platform and on a
8176 realtime processor to compare the behavior:
ObtainQueue
ForLoop N times
EnqueueElement
QueueStatus
EndForLoop
ReleaseQueue
The program worked normally on the development platform
and I could not exhaust memory (virtual memory available).
Then I ran it on the 256 megabyte RAM realtime processor
and when I set the loop trip N high enough, the program acted
abnormally. I got about 216 megabytes on queue before failure.
On the console display of the realtime processor I could see
a message line "Not enough memory to complete this
operation", but the ErrorStatus outputs from all of the queue
VIs showed "no error". The only symptom of abnormal
program operation was the front panel showed program
stopped (visual appearance of run-arrow and abort
button) short of the requested number of iterations.
My question:
Why was "no error" reported from the EnqueueElement
ErrorStatus output and the error was posted to the console
display screen of the RTP?
