|
|
.Fd #include <sys/vnode.h>
|
|
.Fd #include <sys/acl.h>
|
|

.Fn VOP_SETACL "struct vnode *vp" "acl_type_t type" "struct acl *aclp" "struct ucred *cred" "struct proc *p"
|
|
.Sh DESCRIPTION
|
|
This vnode call may be used to set the access control list (ACL) for a file
|
|
or directory.
|
|
.Pp
|
|
Its arguments are:
|
|
.Bl -tag -width type
|
|
.It Ar vp
|

the vnode of the file or directory
|
|
.It Ar type
|
|
the type of ACL to set
|
|
.It Ar aclp

|
|
.It Ar p

|
|

|
|
pointer may be NULL to indicate that the specified ACL should be deleted.
|
|
.Pp
|
|
The
|
|
.Fa cred
|
|
pointer may be NULL to indicate that access control checks are not to be
|
|
performed, of possible. This cred setting might be used to allow the
|
|
kernel to authorize extended attribute changes that the active process might
|
|
not be permitted to make.
|
|
.Pp
|
|
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
|
|
.Xr acl 9 .
|
|
.Sh LOCKS
|
|
The vnode will be locked on entry and should remain locked on return.
|
|
.Sh RETURN VALUES

If the ACL is successfully set, then zero is returned. Otherwise, an
|
|
appropriate error code is returned.
|
|
