========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
答案 0 :(得分：0)
这些类型未定义，因此编译器不知道：
td_NtQuerySystemInformation NtQuerySystemInformation = NULL;
td_NtQueryObject NtQueryObject = NULL;
td_NtDuplicateObject NtDuplicateObject = NULL;
PSYSTEM_PROCESS_INFORMATION，POBJECT_TYPE_INFORMATION等相同。
您需要包含他们的定义。
