  • Article

10/16/2014

This variable specifies the watchdog period, in milliseconds, where the hardware watchdog must be refreshed before system reset.

Syntax

extern DWORD dwWatchDogPeriod;

Parameters

None.

Return Value

None.

Remarks

The default value for this variable is set in Oemglobal.c to 0 (zero), which indicates that a watchdog timer does not exist.

OEMs can override the value of this variable in the call to the OEMInit function to indicate hardware watchdog support.

The kernel watchdog thread refreshes the watchdog based on the value of this variable. If the value is set too small, this can cause substantial performance impact.
