Webpthread_mutex_timedlock 文檔說abs_timeout需要一個CLOCK_REALTIME 。 但是，我們都知道對特定時長進行計時是不合適的（由於系統時間調整）。 有沒有辦法在可移植的CLOCK_MONOTONIC上使 pthread 鎖定超時？ pthread_cond_timedwait 也是如此。 Web但是ret是60（超時），並在pthread_mutex_lock之后掛起。 有人對這三種情況有想法嗎？ FreeBSD中是否有此功能的錯誤，或者我不能以這種方式使用它。 還有其他可以在FreeBSD中實現等待和鎖定的方法嗎？ 謝謝。 =====更新完整代碼以進行復制=====
