127 Note that the pretimeout is the number of seconds before the time
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.
133 There is also a get function for getting the pretimeout::
136 printf("The pretimeout was is %d seconds\n", timeout);
138 Not all watchdog drivers will support a pretimeout.
