open()ing a named pipe with no current readers

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

I guess that's a rater silly/basic question, but ...

Is there a way to open(.. O_WRONLY ..) an existing named pipe that 
currently has no reader such that
-- the open() will neither block nor fail
-- subsequent write()s to that fd will
	-- succeeed if someone started reading in the meantime
	-- block/return EWOULDBLOCK if still no-one is reading
?

Of course there's the work-around of lazily open()ing the fd before each
write() call.
