Hello,
I'm using an AsyncStreams object to write data packets to a file:
Sometimes I noted that a few packets get lost (the number of packets inside outFile is lower than packet_counter).
I don't know how this happens, I suspect this could be due to a sort of buffer overrun inside the AsyncStreams thread (may be the internal queue overruns?).
In any case AStreamWriter_Error() subroutine is never called.
What can I do to avoid this loss of data?
Is there a way to know if asyncFile can't accept further data so to avoid to call asyncFile.Write(data) during this condition?
Any idea on how to fix this issue will be greatly appreciated
