IMPLEMENTATION GUIDELINES
















Before call






    

  • 

    The parameter task must be a valid task object id.
    

    • 

  • 

    This id may be:
    

    

      

    • 

      the calling task’s own id read by calling PxGetId() (V)
      

      • 

    • 

      the return value of a PxTaskCreate() call (V)
      

      • 

    • 

      the result of a nameserver query (V)
      

      • 

    • 

      part of a message sent by another task (V)
      

      • 

    

    

    • 

  • 

    Additionally the task id may be checked with PxTaskCheck() (F).
    

    • 

  • 

    buffer should point to a valid memory area, where the task’s name is stored.
    

    • 

  • 

    bufsize should be a constant or a sizeof() operator (V).
    

    • 



















After call






    

  • 

    The function returns PXERR_NOERROR if the task’s name could be stored. Any other return value describes an error, which has to be interpreted (C).
    

    • 



















Best Practice






    

  • 

    No restrictions.
