The following code example uses the SignalAndWait(WaitHandle, WaitHandle) method overload to allow the main thread to signal a blocked thread and then wait until the thread finishes a task. The example starts five threads, allows them to block on an EventWaitHandle created with the EventReset...

SignalAndWait,它允许线程向一个等待句柄发出信号,并立即等待另一个等待句柄。 WaitAll,它允许线程等待,直到数组中的所有等待句柄收到信号。 WaitAny,它允许线程等待,直到一组指定的等待句柄中的任何一个被发出信号。 这些方法的重载提供了放弃等待的超时间隔,以及进入等待之前退出同步上下文的机会,从而允许其他线程使用...
若要發出物件的訊 EventWaitHandle 號,然後藉由呼叫 SignalAndWait 方法來等候物件,用戶必須具有 Synchronize 和Modify 存取權。 這個建構函式相當於建立 NTAccount 物件,方法是傳遞 identity 至NTAccount.NTAccount(String) 建構函式,並將新建立 NTAccount 的對象傳遞至 EventWaitHandleAccessRule(IdentityReference, Even...
HRESULT WaitOnSignal( DWORD timeOutInMs ); Parameters timeOutInMs The timeout value in milliseconds. Specifying INFINITE will result in the call blocking until the synchronization object is signaled. Return value Returns an HRESULT value, including but not limited to the follow...
simba@ubuntu:~/Documents/code/linux_programming/APUE/process$ ./wait this is parent this is child ret=7156, pid=7156 child exited abnormal signal number=6 说明子进程被信号异常终止,因为我们调用了abort(), 即产生SIGABRT信号将子进程终止,可以查到此信号序号为6。如果我们不使用abort 而是exit(100), ...
If unsuccessful, sigtimedwait() returns -1 and sets errno to one of the following values: Error Code Description EAGAIN No signal specified by set was generated within the specified time out period. EINTR The wait was interrupted by an unblocked, caught signal. No further waiting will occur ...
