参数签名

描述

clear_barrierclear_barrierClearBarrierClearBarrierClearBarrierclear_barrier destroys the barrier object given in BarrierHandleBarrierHandleBarrierHandleBarrierHandlebarrierHandlebarrier_handle. No threads should be waiting on the barrier at the time clear_barrierclear_barrierClearBarrierClearBarrierClearBarrierclear_barrier is called. After calling clear_barrierclear_barrierClearBarrierClearBarrierClearBarrierclear_barrier, the barrier can no longer be used. The handle BarrierHandleBarrierHandleBarrierHandleBarrierHandlebarrierHandlebarrier_handle becomes invalid.
