Re: isEmptyChan, System.Posix.Signals

In local.glasgow-haskell-users, you wrote:

1. 'isEmptyChan x' blocks if x is empty and some other thread is waiting to read from x:

Prelude Control.Concurrent> x <- newChan Prelude Control.Concurrent> forkIO $ readChan x Prelude Control.Concurrent> empty <- isEmptyChan x *** Exception: thread blocked indefinitely

Is that the intended behaviour? Is it possible to make a non-blocking version?

This is a known limitation. Search the mailinglist-archives for a proposed fix. -- http://www-i2.informatik.rwth-aachen.de/stolz/ *** PGP *** S/MIME L-Attriwutgrammatik
