TestWaitForA429Word

Valid for: CANoe DE • CANoe:lite DE • CANoe4SW DE • CANoe4SW:lite DE

​
Function Syntax

  • long TestWaitForA429Word (dbA429Word aWord, dword aTimeout);
  • long TestWaitForA429Word (dword aLabel, dword aTimeout);
  • long TestWaitForA429Word (dword aTimeOut);

​
Description

Wait for the occurrence of the specified word aWord. If the ARINC word does not occur before the expiration of the time aTimeout, the wait condition is resolved nevertheless. If no specific ARINC word is given, the wait condition is resolved on any word. If ARINC word events are delivered from different buses, the context has to be adjusted correctly (SetBusContext). The function handles only incoming and error-free ARINC words.

​
Parameters

  • aWord: Event connected to ARINC word from an assigned database.
  • aLabel: Event connected to ARINC label [1 .. 255].
  • aTimeout: Maximum time that should be waited [ms]; Transmission of 0: no timeout controlling.

​
Return Values

  • -2: Resume due to constraint violation
  • -1: General error (e.g., functionality not available)
  • 0: Resume due to timeout
  • 1: Resume due to event occurred
