GetExplicitEntriesFromAcl
[New - Windows NT]
The GetExplicitEntriesFromAcl function retrieves an array of EXPLICIT_ACCESS structures that describe the access-control entries (ACEs) in an
access-control list (ACL).
DWORD GetExplicitEntriesFromAcl(
PACL pacl,
| // pointer to the ACL from which to get entries
| PULONG pcCountOfExplicitEntries,
| // receives number of entries in the list
| PEXPLICIT_ACCESS * pListOfExplicitEntries
| // receives pointer to list of entries
| );
|
|
Parameters
pacl
Pointer to an ACL from which to get ACE information.
pcCountOfExplicitEntries
Pointer to a variable that receives the number of EXPLICIT_ACCESS structures returned in the pListOfExplicitEntries array.
pListOfExplicitEntries
Pointer to a variable that receives a pointer to an array of EXPLICIT_ACCESS structures that describe the ACEs in the ACL. If the function succeeds, you
must call the LocalFree function to free the returned buffer.
Return Values
If the function succeeds, the return value is ERROR_SUCCESS.
If the function fails, the return value is a nonzero error code defined in
WINERROR.H.
Remarks
Each entry in the array of EXPLICIT_ACCESS structures describes access control information from an ACE for a trustee. A trustee can be a user, group, or program (such as a Windows
NT service).
Each EXPLICIT_ACCESS structure specifies a set of access rights and an access mode flag that
indicates whether the ACE allows, denies, or audits the specified rights.
For a discretionary ACL (DACL), the access mode flag can be one of the following values from the ACCESS_MODE enumeration.
Value
| Meaning
| SET_ACCESS
| Indicates that an access-allowed ACE for the trustee allows the specified
access rights.
| DENY_ACCESS
| Indicates that an access-denied ACE for the trustee denies the specified
access rights.
|
For a system ACL (SACL), the access mode flag can be a combination of the
following values from the ACCESS_MODE enumeration.
Value
| Meaning
| SET_AUDIT_SUCCESS
| Indicates that a system-audit ACE for the trustee generates audit messages for
successful attempts to use the specified access rights.
| SET_AUDIT_FAILURE
| Indicates that a system-audit ACE for the trustee generates audit messages for
failed attempts to use the specified access rights.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
