[rtl] clearing a fifo

[Markus Weiss <Markus.Weiss@uni-bayreuth.de>]

Hi everybody,

I wrote a small rtl-application to collect data from an ESR-spectrometer
and write it to a fifo (replacing an ugly old OS-9 Box).
However, i have to go shure that the fifo is empty before starting a
measurement. 

What would be the best way to clear a fifo ?  
Is it OK to destroy it and immediately create it again ?

Some time ago there was a discussion in this list about writing 
an ioctl call to get the number of bytes waiting in a fifo.
Has anybody actually done that ?

Thanks 
		Markus
