  • Article

Notifies the USB connector manager framework extension (UcmCx) with the updated charging state of the partner connector.

Syntax

NTSTATUS UcmConnectorChargingStateChanged(
  [in] UCMCONNECTOR       Connector,
  [in] UCM_CHARGING_STATE ChargingState
);

Parameters

[in] Connector

Handle to the connector object that the client driver received in the previous call to UcmConnectorCreate.

[in] ChargingState

One of the UCM_CHARGING_STATE-typed flags that indicates the new charging state.

Return value

UcmConnectorChargingStateChanged returns STATUS_SUCCESS if the operation succeeds. Otherwise, this method can return an appropriate NTSTATUS value.

If the client driver determines that the charging state is non-optimal, it should report slow or trickle charging to UcmCx. Then, the operating system notifies the user of this condition.
