This vnode call may be used to set the access control list (ACL) for a file
or directory.
Its arguments are:
|
| vp
|
| |
The vnode of the file or directory.
|
| type
|
| |
The type of ACL to set.
|
| aclp
|
| |
A pointer to an ACL structure from which to retrieve the ACL data.
|
| cred
|
| |
The user credentials to use in authorizing the request.
|
| td
|
| |
The thread setting the ACL.
|
|
The
aclp
pointer may be
NULL
to indicate that the specified ACL should be deleted.
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
changes that the active process might not be permitted to make.
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).
