# SCC\_GetServiceIds

[Valid for](../../../Shared/FeatureAvailability.md): CANoe DE • CANoe4SW DE

**Note**

* This function can be called only within the assigned callback. The function is used to query the details of a request.
* `<InvalidValueSigned>` and/or `<InvalidValueUnsigned>` can be defined in the XML configuration.
  * These are returned if an optional numeric message parameter was queried by this function but not found.
  * See [Configuration of Vehicle SCC Nodes](../../../CANoeCANalyzer/SmartCharging/SCProcedures/SCCConfigurationVehicleSCCNodes.md) or [Configuration of Chargepoint SCC Nodes](../../../CANoeCANalyzer/SmartCharging/SCProcedures/SCConfigurationChargePointSCCNodes.md).

## Function Syntax

```plaintext theme={null}
long SCC_GetServiceIds(dword ChargeServiceIDs[], dword ServiceListIDs[], long& ChargeServiceIDsCount, long& ServiceListIDsCount);
```

## Description

Returns the **ServiceID** from the **ChargeService** and the **ServiceIDs** from the **ServiceList** sent with the current **ServiceDiscoveryRes** on EVSE side.

This function is meant to help with matching the **SerivceIDs** received from an EV against the information sent within a **ServiceDiscoveryRes** by the EVSE.

Note: This function is only valid during a `SCC_MessageTxInd()` callback with MessageID = 8 (ServiceDiscoveryRes).

## Parameters

* **ChargeServiceIDs**: The destination array of at least size 1 to receive the ServiceID from the ChargeService.
* **ServiceListIDs**: The destination array is large enough to receive the (maximum) number of expected ServiceIDs from the ServiceList as per your SCC\_ChargePoint XML configuration file.
* **ChargeServiceIDsCount**:
  * In: dimension of the destination array
  * Out: The number of charge services
* **ServiceListIDsCount**:
  * In: dimension of the destination array
  * Out: The number of ServiceIDs returned in the ServiceListIDs array, may be 0 (zero) if no ServiceList is contained in the message.

## Return Values

* **0**: error, the message was called in the wrong V2G context, i.e., not during a SCC\_MessageTxInd() with message = ServiceDiscoveryRes.
* **1**: success
* **2**: success, but the specified array dimension was too short. Increase the arrays dimension to receive all data.
