DeleteAce

The DeleteAce function deletes an ACE from an ACL.

An ACE is an access-control entry. An ACL is an access-control list.

BOOL DeleteAce(
  PACL pAcl,         // access-control list
  DWORD dwAceIndex   // index of ACE position in ACL
);

Parameters

pAcl

[in/out] Pointer to an ACL structure. The ACE specified by the dwAceIndex parameter is removed from this ACL.

dwAceIndex

[in] Specifies the ACE to delete. A value of 0 corresponds to the first ACE in the ACL, 1 to the second ACE, and so on.

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

An application can use the ACL_SIZE_INFORMATION structure retrieved by the GetAclInformation function to discover the size of the ACL and the number of ACEs it contains. The GetAce function retrieves information about an individual ACE.
