- *  @brief Cancel a blocking operation due to ISR.
- *
- *  This method is used to cancel a blocking operation that was
- *  satisfied from an ISR while the thread executing was in the
- *  process of blocking.
- *
- *  This method will restore the previous ISR disable level during the cancel
- *  operation.  Thus it is an implicit _ISR_Enable().
- *
- *  @param[in] sync_state is the synchronization state
- *  @param[in] the_thread is the thread whose blocking is canceled
- *  @param[in] level is the previous ISR disable level
- *
- *  @note This is a rare routine in RTEMS.  It is called with
- *        interrupts disabled and only when an ISR completed
- *        a blocking condition in process.
