如何用WindowsAPI取得一个进程的所有线程句柄

我能取得一个进程所有线程的ID，但不会取所有线程的句柄。。？

Answer 1

#include <tlhelp32.h>

int GetProcessThreadList(DWORD th32ProcessID) //进程的ID
{
HANDLE hThreadSnap;
THREADENTRY32 th32;

hThreadSnap = CreateToolhelp32Snapshot(TH32CS_SNAPTHREAD, th32ProcessID);

if (hThreadSnap == INVALID_HANDLE_VALUE)
{
return 1;
}

th32.dwSize = sizeof(THREADENTRY32);
if (!Thread32First(hThreadSnap, &th32))
{
CloseHandle(hThreadSnap);
return 1;
}

do
{
if (th32.th32OwnerProcessID == th32ProcessID)
{
printf("ThreadID: %ld\n", th32.th32ThreadID); //显示找到的线程的ID
}
}while(Thread32Next(hThreadSnap, &th32));

CloseHandle(hThreadSnap);
return 0;
}
