Linkoping University Sweden Keywords: Dear netland, we are using X windows and try to use starbase on a window but run into severe problems: Why do the starbase call gopen() in, seemingly, randomness sometimes fail, sometimes succeed when used with X-windows? Our call is gopen(device_string, OUTDEV, "hp98550") and the program is linked with -ldd98550. The error message is "starbase error 3: device kind is not supported for the specified device" But the call works beautiful sometimes ?? -- ----------------------------------------------------------------------- Torbjorn Kronander tobbe@isy.liu.se Dept. of EE Linkoping University Sweden ph +46 13 28 22 07

I don't know know for sure, but gopen takes four arguments, not just three (the fourth one being mode). I suspect that on the times that it fails there is junk on the stack that is an invalid mode for your device. -- Chan Benson HP Fort Collins

The gopen function has four parameters, but you only passed it three. The call will fail when the random stack value which is read as the 'mode' parameter has both the INT_XFORM and FLOAT_XFORM flags set. Mike Stroyan, stroyan@hpfcla.hp.com
