使用ToolHelperAPI枚举OS中所有的线程和进程

BOOL EnumProcessInfo()
{
 //定义进程信息结构
 PROCESSENTRY32 pe32 = {sizeof(pe32)};
 //创建系统当前的进程快照
 HANDLE hProcessShot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
 if (hProcessShot == INVALID_HANDLE_VALUE)
 {
  return false;
 }
 //输出进程信息到文件
 ofstream fout("EnumInfo_ToolHelp_process.txt");

 //循环枚举进程信息
 char szBuf[300] = {0};
 if (Process32First(hProcessShot, &pe32))
 {
  do
  {
   memset(szBuf, 0, sizeof(szBuf));
   //把宽字符的进程名转化为ANSI字符串
   WideCharToMultiByte(CP_ACP, 0, pe32.szExeFile,
    wcslen(pe32.szExeFile),szBuf,sizeof(szBuf),NULL,NULL);
   fout<<"Process: "<<szBuf<<endl;
   fout<<'\t'<<"Usage       :"<<pe32.cntUsage<<endl;

 fout.close();

 return true;
}

BOOL EnumThreadInfo()
{
