pending

pending函数用于获取当前策略程序正在运行的并发线程数。

pending()函数返回当前策略程序正在运行的并发线程数。

number

pending()

function threadFun1() {
    Log("threadFun1")
    Sleep(3000)
}

function threadFun2() {
    for (var i = 0; i < 3; i++) {
        LogStatus(_D(), "print from threadFun2")
        Sleep(3000)
    }
}

function main() {
    Log(`begin -- threading.pending():`, threading.pending())

    var t1 = threading.Thread(threadFun1)
    var t2 = threading.Thread(threadFun2)
    Log(`after threading.Thread -- threading.pending():`, threading.pending())

    t1.join()
    t2.join()
    Log(`after thread.join -- threading.pending():`, threading.pending())
}

创建两个并发运行的线程，在不同时间节点调用pending()函数。

策略main()函数开始运行时直接调用pending()函数会返回1，因为策略main()函数所在的主线程也是一个pending中的线程。
