Function sd_notify::watchdog_enabled
source · [−]Expand description
Asks the service manager for enabled watchdog.
If the unset_env
parameter is set, the WATCHDOG_USEC
and WATCHDOG_PID
environment variables
will be unset before returning. Further calls to watchdog_enabled
will fail, but
child processes will no longer inherit the variable.
See sd_watchdog_enabled(3)
for details.
Example
let mut usec = 0;
let enabled = sd_notify::watchdog_enabled(true, &mut usec);
