I'm confused - newlib's clearerr calls __sclearerr, but I can't find
that anywhere. cygwin.dindefines clearerr and _clearerr, but I can't
find them in the source..
In testing the fifo semantics, I've found that the expected behaviour
for a fifo on freeBSD is that clearerr() should re-open the fifo,
allowing further writes to take take place..
i.e.
a reader can loop
clearerr()
read to eof
and the pipe can have multiple separate writers write to the pipe and
exit. Without clearerr or a rewind(), the pipe gets marked eof and stays
eof.
most OS's seem to simply use rewind() to the same effect, so I'm
implementing that. The question I have is: will clearerr() actually call
any cygwin code?
