118 Note that the pretimeout is the number of seconds before the time
120 the pretimeout. So, for instance, if you set the timeout to 60 seconds
121 and the pretimeout to 10 seconds, the pretimeout will go off in 50
122 seconds. Setting a pretimeout to zero disables it.
124 There is also a get function for getting the pretimeout:
127 printf("The pretimeout was is %d seconds\n", timeout);
129 Not all watchdog drivers will support a pretimeout.

196 If the pretimeout feature is used (WDIOF_PRETIMEOUT), then set_timeout must

200 * set_pretimeout: this routine checks and changes the pretimeout value of
