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

## Function Syntax

* `long mostApIsAddressed(long fblockID, long instID); // form 1`
* `long mostApIsAddressed(mostAmsMessage * msgCommand); // form 2`

## Description

`mostApIsAddressed` checks whether the functional MOST address `{fblockID, instID}` matches the CAPL node function blocks assigned via [mostApRegister()](CAPLfunctionMOSTApRegister.md) or [mostApRegisterEx()](CAPLfunctionMOSTApRegisterEx.md). The functional address is permitted to contain wildcard symbols.

This function can be used to determine whether an incoming command message is destined for the CAPL node.

## Parameters

* **fblockID**: Function block identifier of the functional address.
* **instID**: Instance identifier of the functional address.
* **msgCommand**: Received command message containing the functional address.

## Return Values

* **1**: If a MOST application simulated by this CAPL node is addressed.
* **0**: Otherwise
* **\<0**: See [error codes](../CAPLfunctionsMOSTErrorCodes.md)
