Hi, just as short update:
The cdrw source pointed to by Dagobert Michelsen showed me how to open without long delays. One could have guessed: it is option O_NDELAY. The behavior is described in man -s 2 open. Obviously the traditional open() call by libcdio waited until START UNIT had succeeded. So we can for now omit the dependncy on libdevinfo. Many thanks to Dago. :)) Have a nice day :) Thomas
