ACE

An ACE is an access-control entry (ACE) in an access-control list (ACL).

Following are the currently defined ACE types:

System-alarm ACEs are not supported in the current version of Windows NT.

Remarks

An ACL contains a list of ACEs. An ACE defines access to an object for a specific user or group or defines the types of access that generate system-administration messages or alarms for a specific user or group. The user or group is identified by a security identifier (SID).

Each ACE starts with an ACE_HEADER structure. The format of the data following the header varies according to the ACE type specified in the header.
