[Live-devel] Re: One (maybe two) little bug in Makefile.tail

Matteo,

Thanks for noting the Makefile problem; it has been fixed in the most 
recent release (2004.03.27).

But if you *don't* call "write(wr_fd,"w",1);", exactly the same thing will 
happen: When you return to the event loop (see 
"BasicTaskScheduler0::doEventLoop()"), the watch variable will be non-zero, 
and you'll return from the event loop.  Creating the 'fd's, and calling 
"turOnBackgroundReadHandling()" adds nothing.
