下面是我的程序,当进程在使用 windbg 的 WaitForSingleObject() 调用中被阻塞时,我试图获取调用堆栈。奇怪的是当进程阻塞时,windbg 只打印出非常奇怪的堆栈。

// process2.cpp : Defines the entry point for the console application.

#include "stdafx.h"
#include "windows.h"
HANDLE g_hWriteEvent;
int _tmain(int argc, _TCHAR* argv[])
{
g_hWriteEvent = OpenEvent(
EVENT_ALL_ACCESS,
FALSE,
TEXT("WriteEvent")
);
if (g_hWriteEvent == NULL) {
printf("OpenEvent error (%d)\n", GetLastError());
return 0;
}
// while (1);
WaitForSingleObject(g_hWriteEvent, INFINITE);
return 0;
}
请注意,如果我取消注释该while(1)
行,则 windbg 可以识别该进程在_tmain
函数中阻塞。
谢谢。斌
