SYNOPSIS
PxTmode_t PxClearModebits (PxTmode_t modebits);
ARGUMENTS






modebits




The new modebits

















RETURN VALUES






    

  • 

    The old value of modebits
    

    • 







DESCRIPTION










PxClearModebits clears the bits modebits in the calling task’s task control block. This re-enables the corresponding mechanism.














The task mode specifies how a task reacts on external events. More specifically, the task mode contains the following modebits:














    

  • 

    PXTmodeDisableAborts to control the abort mechanism
    

    • 

  • 

    PXTmodeDisableTimeslicing to control the timeslice mechanism
    

    • 























IMPLEMENTATION GUIDELINES
















Before call






    

  • 

    modebits may be a combination of the following bits (V):
    

    

      

    • 

      PXTmodeDisableAborts
      

      • 

    • 

      PXTmodeDisableTimeslicing
      

      • 

    

    

    • 



















After call






    

  • 

    PxGetError must be called to check if an error has occurred. (F)
    

    • 



















Best Practice






    

  • 

    No restrictions.
