KsGenerateThermalEvent function (ks.h)

  • Article

This function is used by clients (miniport drivers) that do not want to subscribe to the thermal manager, but want to do their own thermal management.

There is a check that verifies whether the miniport driver has the query interface support for a thermal manager (for example, the device is actively managed by a thermal manager). In cases of devices managed by a thermal manager, this call is rejected.

Syntax

KSDDKAPI NTSTATUS KsGenerateThermalEvent(
  [in] PVOID                  Object,
  [in] KSDEVICE_THERMAL_STATE Value
