get_current_hthread_idget_current_hthread_idGetCurrentHthreadIdGetCurrentHthreadIdget_current_hthread_id (算子名称)

名称

get_current_hthread_idget_current_hthread_idGetCurrentHthreadIdGetCurrentHthreadIdget_current_hthread_id — Return the HALCON thread ID of the current thread.

参数签名

描述

get_current_hthread_idget_current_hthread_idGetCurrentHthreadIdGetCurrentHthreadIdGetCurrentHthreadIdget_current_hthread_id returns a thread ID that represents the currently running thread in HThreadIDHThreadIDHThreadIDHThreadIDHThreadIDhthread_id. This ID is identical to the windows thread ID or the POSIX thread ID on UNIX platforms and is also returned by the par_start operation of the HDevEngine. It can later be used to interrupt operators that are executed in this thread using interrupt_operatorinterrupt_operatorInterruptOperatorInterruptOperatorInterruptOperatorinterrupt_operator.

运行信息

• 多线程类型:可重入(与非独占操作符并行运行)。
• 多线程作用域:全局(可以从任何线程调用)。
• 未经并行化处理。

参数表

例程 (HDevelop)

global tuple HThreadID
get_current_hthread_id (HThreadID)
* call some slow operator...

* In a different thread
wait_seconds(2)
* Interrupt the long-running operator in the other thread
interrupt_operator (HThreadID, 'break')

结果

If the current thread can be determined, get_current_hthread_idget_current_hthread_idGetCurrentHthreadIdGetCurrentHthreadIdGetCurrentHthreadIdget_current_hthread_id returns 2 ( H_MSG_TRUE) . Otherwise an exception is raised.
