EDIT: Sorry, my mistake; I think I was passing a CALuint device ordinal ( -- as needed for calDeviceGetInfo() and calDeviceGetAttribs() -- ) rather than the required CALdevice device handle into the second argument to calDeviceGetStatus().
Does anybody know if calDeviceGetStatus() is working for linux 64-bit? I seem to be getting the error string "A handle parameter is invalid". (Nb. calDeviceGetInfo() and calDeviceGetAttribs() seem to be working.)
