30.Dt VOP_ACLCHECK 9
31.Sh NAME
32.Nm VOP_ACLCHECK
33.Nd check an access control list for a vnode
34.Sh SYNOPSIS
35.In sys/param.h
36.In sys/vnode.h
37.In sys/acl.h
38.Ft int
39.Fn VOP_ACLCHECK "struct vnode *vp" "acl_type_t type" "struct acl *aclp" "struct ucred *cred" "struct thread *td"
40.Sh DESCRIPTION
41This vnode call may be used to determine the validity of a particular access
42control list (ACL) for a particular file or directory.
43.Pp
44Its arguments are:
45.Bl -tag -width type
46.It Ar vp
47the vnode of the file or directory
48.It Ar type
49the type of ACL to check
50.It Ar aclp
51a pointer to an ACL structure from which to retrieve the ACL data
52.It Ar cred
53the user credentials to use in authorizing the request
54.It Ar td
55the thread checking the ACL
56.El
57.Pp
58The
59.Fa cred
60pointer may be NULL to indicate that access control checks are not to be
61performed, if possible. This cred setting might be used to allow the
62kernel to authorize ACL verification that the active process might not be
63permitted to do.
64.Pp
65The vnode ACL interface defines the syntax, and not semantics, of file and
66directory ACL interfaces. More information about ACL management in kernel
67may be found in
68.Xr acl 9 .
69.Sh LOCKS
70No locks are required to call this vnode method, and any locks held on
71entry will be held on exit.
72.Sh RETURN VALUES
73If the
74.Fa aclp
75pointer points to a valid ACL of type
76.Fa type
77for the object
78.Fa vp ,
79then zero is returned. Otherwise, an appropriate error code is returned.
80.Sh ERRORS
81.Bl -tag -width Er
82.It Bq Er EINVAL
83The ACL type passed is invalid for this vnode, or the ACL data is invalid.
84.It Bq Er EACCES
85The file or directory ACL does not permit access.
86.It Bq Er ENOMEM
87Sufficient memory is not available to fulfill the request.
88.It Bq Er EOPNOTSUPP
