RtResetWatchdog

RtResetWatchdog resets the watchdog timer counter on the specified RTSS core(s).

NOTE: This function is only supported in the RTSS environment. It cannot be called from a Windows application linked to RTX64.

);

Parameters

Affinity mask that specifies the RTSS core(s) on which the watchdog timer counter will be reset. See Specifying a Processor Affinity Bitmask for more information.

Remarks

RtResetWatchdog should be called in a higher priority thread than the potential timeout-causing thread, or on a free core. See Runaway Thread Management for more information on the use of the watchdog timer.
