SYNOPSIS    [Toc]    [Back]

     #include <sys/param.h>

DESCRIPTION    [Toc]    [Back]

     Each device has an enabled flag associated with it.  A device is enabled
     by default when it is created but may be disabled (for instance to prevent
 a destructive or time consuming probe attempt).  To disable a
     device, call device_disable(), to re-enable it, call device_enable() and
     to test to see if a device is enabled, call device_is_enabled().
