This class is a wrapper for an ACL (access-control list) structure.
class CAcl
Remarks
The ACL structure is the header of an ACL (access-control list). An ACL includes a sequential list of zero or more ACEs (access-control entries). The individual ACEs in an ACL are numbered from 0 to n-1, where n is the number of ACEs in the ACL. When editing an ACL, an application refers to an access-control entry (ACE) within the ACL by its index.
There are two ACL types:
Discretionary
System
A discretionary ACL is controlled by the owner of an object or anyone granted WRITE_DAC access to the object. It specifies the access particular users and groups can have to an object. For example, the owner of a file can use a discretionary ACL to control which users and groups can and cannot have access to the file.
An object can also have system-level security information associated with it, in the form of a system ACL controlled by a system administrator. A system ACL can allow the system administrator to audit any attempts to gain access to an object.
For more details, see the ACL discussion in the Windows SDK.
