Dで新しいファイルを作成しようとしています:c /c++でドライブ
Windowsの書き込み権限を取得するためのこのコードを見つけましたが、機能しません
誰かが私がC++で新しいのを手伝ってくれますか?
BOOL SetPrivilege(

コンソールの出力は次のようになります。
OpenProcessToken() is OK
LookupPrivilegeValue() is OK
tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED
AdjustTokenPrivileges() is OK, last error if any: 1300
Should be 0, means the operation completed successfully = ERROR_SUCCESS
The SetPrivilege() return value: 1
LookupPrivilegeValue() is OK
tp.Privileges[0].Attributes = 0
AdjustTokenPrivileges() is OK, last error if any: 1300
Should be 0, means the operation completed successfully = ERROR_SUCCESS
The SetPrivilage() return value: 1
