DESCRIPTION










PxToChange changes the timeout and events associated with To. It implicitly stops To.






















IMPLEMENTATION GUIDELINES
















Before call






    

  • 

    ToId must be a valid PXROS-HR timeout object created with a PxToRequest call (V). The validity of ToId may also be checked by the PxToIsValid macro (F).
    

    • 

  • 

    The timeout parameter must have a plausible value. It should be a constant or the result of a PxTickGetTicksFromMilliSeconds call (V);
    

    • 

  • 

    The parameter events contains an event bit  and should not be zero. Typically the event is a constant (V).
    

    • 



















After call






    

  • 

    The function returns PXERR_NOERROR if the timout could be changed. Any other return value describes an error, which has to be interpreted (C).
    

    • 



















Best Practice






    

  • 

    No restrictions.
