如何获取属于某个进程的打开的句柄数? [英] How to get count of opened handles that belongs to a certain process?

问题描述

您可以使用程序 Process Explorer 来查看有多少个句柄正在运行应用程序有. Delphi代码有没有办法获取这个数字?我对跟踪应用程序本身的数量感兴趣；找不到Process Explorer正在执行的其他应用程序使用的句柄数.

You can use the program Process Explorer to see how many handles running applications have. Is there a way with Delphi code to get this number? I am interested in tracking the number for the application itself; not to find the number of handles used by other applications as Process Explorer is doing.

我的目的是让应用程序跟踪/检测可能的资源泄漏.

My intention is for the application to track/detect possible resource leaks.

推荐答案

使用

Use the GetProcessHandleCount function. This API function is in recent versions of Delphi imported by the Winapi.Windows unit (so you can omit the presented one):

function GetProcessHandleCount(hProcess: THandle; var pdwHandleCount: DWORD): BOOL; stdcall;
  external 'kernel32.dll';

procedure TForm1.Button1Click(Sender: TObject);
var
  HandleCount: DWORD;
begin
  if GetProcessHandleCount(GetCurrentProcess, HandleCount) then
    ShowMessage('Handle count: ' + IntToStr(HandleCount));
end;
