|poll()| vs. partial reads from FIFO...


Hi!

----

I'm currently writing a small application which should use |poll()| on
multiple FIFOs (created via /usr/bin/mkfifo) but I am getting a weired
behaviour: The FIFOs are fed from other processes (one FIFO per process)
which never terminate and only write data from time to time into the
FIFOs and the consumer application uses |poll()| to wait for incoming
data.

The (weired) problem is now that if the consumer only reads some data
from a FIFO file descriptor and not all queued data then the |revent|
field for this pollfd entry will return |0| on the following |poll()|
call (even if there are still data queued). Is this the correct
behaviour ?

Bye,
Roland
