H A Dwatchdog-api.rst98 representing the timeout in seconds. The driver returns the real
104 printf("The timeout was set to %d seconds\n", timeout);
106 This example might actually print "The timeout was set to 60 seconds"
113 printf("The timeout was is %d seconds\n", timeout);
127 Note that the pretimeout is the number of seconds before the time
128 when the timeout will go off. It is not the number of seconds until
129 the pretimeout. So, for instance, if you set the timeout to 60 seconds
130 and the pretimeout to 10 seconds, the pretimeout will go off in 50
131 seconds. Setting a pretimeout to zero disables it.
