有没有办法在Windows中枚举给定PID的进程,并获取其所有已打开的句柄(锁定的文件等)列表?
编辑:语言无所谓。如果是.NET,我会很高兴;如果是WinApi(C),也不会有问题。如果是其他语言,我想我可以重写它 :-)
void ListHandles( DWORD processID, LPCTSTR lpFilter )

希望这能帮到你。
这里有一个示例,使用DDK中的ZwQueryProcessInformation
。DDK现在已被称为“WDK”,可以在MSDN上获得。如果您没有MSDN,显然您也可以从这里获取。
我没有尝试过,只是通过谷歌搜索回答了你的问题。

NtQuerySystemInformation
,它会返回所有句柄,然后需要迭代并按所需PID进行过滤。据我所知,没有办法向操作系统请求仅针对一个进程的句柄。 - Bartek Banachewicz
