int xxprint(dev_t dev, char *str)
The print(9E) entry point is called by the system to display a message about an exception it has detected. print(9E) should call cmn_err(9F) to post the message to the console on behalf of the system. Here is an example:
static int xxprint(dev_t dev, char *str) { cmn_err(CE_CONT, "xx: %s\n", str); return (0); }
