The AddAccessDeniedAce function adds an access-denied ACE to an ACL. The access is denied to a specified SID.
An ACE is an access-control entry. An ACL is an access-control list. A SID is a security identifier.
BOOL AddAccessDeniedAce(
PACL pAcl, // pointer to access-control list
DWORD dwAceRevision, // ACL revision level
DWORD AccessMask, // access mask
PSID pSid // pointer to security identifier
);
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
The AddAccessAllowedAce and AddAccessDeniedAce functions add a new ACE to the end of the list of ACEs for the ACL. These functions do not automatically place the new ACE in the proper canonical order. It is the caller's responsibility to ensure that the ACL is in canonical order by adding ACEs in the proper sequence. For Windows NT versions 4.0 and earlier, the canonical order for a DACL places all access-denied ACEs before any access-allowed ACEs.
The ACE_HEADER structure placed in the ACE by the AddAccessDeniedAce function specifies a type and size, but provides no ACE flags.
