## Function Syntax

* `dword linSimulateETFCollision (dword etfId); // form 1`
* `dword linSimulateETFCollision (dword etfId, dword respLength, dword numCollisions, byte dataBytes[]); // form 2`

## Description

This function can be used to cause collisions for next coming header(s) of an event-triggered frame.

## Parameters

* **etfId**: LIN frame identifier in the range 0 .. 59
* **respLength**: Number of databytes to be sent as the response on the header of the event-triggered frame. Value range: 1..9. Default: 1
* **numCollisions**: Number of times the specified response has to be applied. Value range: 1..255. Default: 1
* **Databytes**: Array of databytes to be sent as the response. The size of the array shall correspond to the respLength parameter. Default: NULL

## Return Values

On success, a value unequal to zero, otherwise zero.
