Enumerating threads in Windows
提问by bdonlan
How can I enumerate all of the threads in a process given a HANDLE to the process (or a process ID)? I'm interested in doing this so I can further do an EnumThreadWindowson each thread.
如何枚举进程中的所有线程，给进程（或进程 ID）一个 HANDLE？我有兴趣这样做，所以我可以在每个线程上进一步执行EnumThreadWindows。

Enumerating threads in a processat MSDN Blogs.
Code snippet from there:
那里的代码片段：
#include <stdio.h>
#include <windows.h>
#include <tlhelp32.h>
int __cdecl main(int argc, char **argv)
{
HANDLE h = CreateToolhelp32Snapshot(TH32CS_SNAPTHREAD, 0);
if (h != INVALID_HANDLE_VALUE) {
THREADENTRY32 te;
te.dwSize = sizeof(te);
if (Thread32First(h, &te)) {
do {
if (te.dwSize >= FIELD_OFFSET(THREADENTRY32, th32OwnerProcessID) +
sizeof(te.th32OwnerProcessID)) {
printf("Process 0x%04x Thread 0x%04x\n",
te.th32OwnerProcessID, te.th32ThreadID);
}
te.dwSize = sizeof(te);
} while (Thread32Next(h, &te));
}
CloseHandle(h);
}
return 0;
}

The ToolHelp library gives an API for snapshotting processes and enumerating their threads (amongst other properties). See MSDN for details.
ToolHelp 库提供了用于对进程进行快照并枚举其线程（以及其他属性）的 API。 有关详细信息，请参阅 MSDN。
