DEVICE_QUIET(9)		 BSD Kernel Developer's	Manual	       DEVICE_QUIET(9)

NAME
     device_quiet, device_verbose, device_is_quiet -- manipulate device	quiet
     flag

SYNOPSIS
     #include <sys/param.h>
     #include <sys/bus.h>

     void
     device_quiet(device_t dev);

     void
     device_verbose(device_t dev);

     int
     device_is_quiet(device_t dev);

DESCRIPTION
     Each device has a quiet flag associated with it.  A device	is verbose by
     default when it is	created	but may	be quieted to prevent printing of the
     device identification string during attach	and printing of	a message dur-
     ing detach.  To quiet a device, call device_quiet() during	a device
     driver probe routine.  To re-enable probe messages, call
     device_verbose().	To test	to see if a device is quieted, call
     device_is_quiet().

     Devices are implicitly marked verbose after a driver detaches.
