AddAce
The AddAce
function adds one or more ACEs to a specified ACL.
An ACE is an
access-control entry. An ACL is an access-control list.
BOOL AddAce(
|
PACL pAcl, |
// pointer to
access-control list |
|
DWORD dwAceRevision, |
// ACL revision
level |
|
DWORD dwStartingAceIndex, |
// index of ACE
position in ACL |
|
LPVOID pAceList, |
// pointer to one
or more ACEs |
|
DWORD nAceListLength |
// size of buffer
for ACEs |
|
); |
|
Parameters
pAcl
Pointer to an
ACL
structure. This function adds an ACE to this ACL.
dwAceRevision
Specifies the
revision level of the ACL being modified. Currently, this value must be
ACL_REVISION.
dwStartingAceIndex
Specifies the
position in the ACL s list of ACEs at which to add new ACEs. A value of zero
inserts the ACEs at the beginning of the list. A value of MAXDWORD appends the
ACEs to the end of the list.
pAceList
Pointer to a
list of one or more ACEs to be added to the specified ACL. The ACEs in the list
must be stored contiguously.
nAceListLength
Specifies the
size, in bytes, of the input buffer pointed to by the pAceList
parameter.
Return Values
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.
Remarks
Applications
frequently use the FindFirstFreeAce and GetAce functions when
using the AddAce function to manipulate an ACL. In addition, the ACL_SIZE_INFORMATION structure retrieved by the GetAclInformation
function contains the size of the ACL and the number of ACEs it contains.
