70 The ioctl API:
72 All conforming drivers also support an ioctl API.
74 Pinging the watchdog using an ioctl:
76 All drivers that have an ioctl interface support at least one ioctl,
77 KEEPALIVE.  This ioctl does exactly the same thing as a write to the
82 		ioctl(fd, WDIOC_KEEPALIVE, 0);
86 the argument to the ioctl is ignored.
91 fly with the SETTIMEOUT ioctl, those drivers have the WDIOF_SETTIMEOUT
98     ioctl(fd, WDIOC_SETTIMEOUT, &timeout);
105 current timeout using the GETTIMEOUT ioctl.
107     ioctl(fd, WDIOC_GETTIMEOUT, &timeout);
114 the reason for the last reboot of the system.  The GETSUPPORT ioctl is
118 	ioctl(fd, WDIOC_GETSUPPORT, &ident);
175     ioctl(fd, WDIOC_GETSTATUS, &flags);
179     ioctl(fd, WDIOC_GETBOOTSTATUS, &flags);
184 Some drivers can measure the temperature using the GETTEMP ioctl.  The
188     ioctl(fd, WDIOC_GETTEMP, &temperature);
190 Finally the SETOPTIONS ioctl can be used to control some aspects of
192 supporting thiss ioctl.
195     ioctl(fd, WDIOC_SETOPTIONS, options);
218 	silly?  To be able to use the ioctl, the device must be open
233 	The timeout can be set using the SETTIMEOUT ioctl and defaults
252 	driver supports the SETTIMEOUT ioctl.
