This vnode call may be used to retrieve the access control list (ACL) from a
file or directory.
Its arguments are:
|
| vp
|
| |
The vnode of the file or directory.
|
| type
|
| |
The type of ACL to retrieve.
|
| aclp
|
| |
A pointer to an ACL structure to receive the ACL data.
|
| cred
|
| |
The user credentials to use in authorizing the request.
|
| td
|
| |
The thread requesting the ACL.
|
|
The
cred
pointer may be
NULL
to indicate that access control checks are not to be performed, if possible.
This cred setting might be used to allow the kernel to authorize ACL
retrieval that the active process might not be permitted to do.
The vnode ACL interface defines the syntax, and not semantics, of file and
directory ACL interfaces.
More information about ACL management in kernel may be found in
acl(9).
