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? Rob
