問題: 在很多程式中, 我們會需要知道使用者是否有系統管理員權限. 怎麼寫一個程式來做到?
解答: 請使用以下的程式. 此程式會回傳"True"如果使用者有系統管理員權限.
BOOL IsUserAdmin(VOID)
/*++
Routine Description: This routine returns TRUE if the caller's process
is a member of the Administrators local group. Caller is NOT expected
to be impersonating anyone and is expected to be able to open its own
process and process token.
Arguments: None.
Return Value:
TRUE - Caller has Administrators local group.
FALSE - Caller does not have Administrators local group. --
*/
{
BOOL b;
SID_IDENTIFIER_AUTHORITY NtAuthority = SECURITY_NT_AUTHORITY;
PSID AdministratorsGroup;
b = AllocateAndInitializeSid(
&NtAuthority,
2,
SECURITY_BUILTIN_DOMAIN_RID,
DOMAIN_ALIAS_RID_ADMINS,
0, 0, 0, 0, 0, 0,
&AdministratorsGroup);
if(b)
{
if (!CheckTokenMembership( NULL, AdministratorsGroup, &b))
{
b = FALSE;
}
FreeSid(AdministratorsGroup);
}
return(b);
}
