# mostNwmFunctionEnable

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

## Function Syntax

```plaintext theme={null}
long mostNwmFunctionEnable(long functionId, long opTypes);
```

## Description

Registers and unregisters a function and its operations with the NetworkMaster.

**Note:** The NetworkMaster will not respond to the new registered function and thus an [on mostMessage](../EventProcedures/CAPLfunctionOnMOSTMessage.md)/[on mostAMSMessge](../EventProcedures/CAPLfunctionOnMOSTAMSMessage.md) handler has to be implemented in the CAPL module of the NetworkMaster.

## Parameters

* **functionId**: Function ID.
* **opTypes (Property/Method)**:
  * `0`: unregisters the function.

  * `1-0xFFFF`: according to the table below.

  * **Bit 0**: OpType = 0x0 (Set/Start)

  * **Bit 1**: OpType = 0x1 (Get/Abort)

  * **Bit 2**: OpType = 0x2 (SetGet/StartResult)

  * **Bit 3**: OpType = 0x3 (Increment/-)

  * **Bit 4**: OpType = 0x4 (Decrement/-)

  * **Bit 5**: OpType = 0x5 (GetInterface/GetInterface)

  * **Bit 6**: OpType = 0x6 (-/StartResultAck)

  * **Bit 7**: OpType = 0x7 (-/AbortAck)

  * **Bit 8**: OpType = 0x8 (-/StartAck)

  * **Bit 9**: OpType = 0x9 (-/ErrorAck)

  * **Bit 10**: OpType = 0xA (-/ProcessingAck)

  * **Bit 11**: OpType = 0xB (-/Processing)

  * **Bit 12**: OpType = 0xC (Status/Result)

  * **Bit 13**: OpType = 0xD (-/ResultAck)

  * **Bit 14**: OpType = 0xE (Interface/Interface)

  * **Bit 15**: OpType = 0xF (Error)
