This vnode call may be used to determine the validity of a particular access
control list (ACL) for a particular file or directory.
Its arguments are:
|
| vp
|
| |
The vnode of the file or directory.
|
| type
|
| |
The type of ACL to check.
|
| 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 checking 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 verification 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).
