谁说-1无效的？ 在这个函数中-1和0xFFFFFFFF是等效的！其次在win7 ring3层没看见说-1 无效 只有为0时才无效

另外你的代码是从ReactOS中提取出来的,不是Windows NT的实现
另外你的代码是Nt
QueryInformationProcess的片段,不是Nt
SetInformationProcess的片段,这真是哈哈哈哈.那么就让我给大家展示一下ReactOS的NtSetInformationProcess中对这个功能的实现吧!
case ProcessQuotaLimits:
DPRINT1("Quota Limits not implemented\n");
Status = STATUS_NOT_IMPLEMENTED;
break;
关于具体实现大家可以自己去WRK的ps\psquery.c:1889(PspSetQuotaLimits)一探究竟
没使用过这些 对于配置比较低的电脑还是有些用处的。
同求
两天没来了，怎么这么吵。
