这是网上找到的代码,我不懂C语言,不知是否有用。
#include <Windows.h>
#include <Aclapi.h>
#pragma comment (lib,"Advapi32.lib")
void main()

HKEY hKey = NULL;
// 获取SAM主键的DACL
dwRet = GetNamedSecurityInfo(SamName, SE_REGISTRY_KEY, DACL_SECURITY_INFORMATION, NULL, NULL, &pOldDacl, NULL, &pSD);
if (dwRet != ERROR_SUCCESS)
{
printf("GetNamedSecurityInfo Error: %d\n", dwRet);
