VOP_SETACL(9)		 BSD Kernel Developer's	Manual		 VOP_SETACL(9)

NAME
     VOP_SETACL	-- set the access control list for a vnode

SYNOPSIS
     #include <sys/param.h>
     #include <sys/vnode.h>
     #include <sys/acl.h>

     int
     VOP_SETACL(struct vnode *vp, acl_type_t type, struct acl *aclp,
	 struct	ucred *cred, struct thread *td);

DESCRIPTION
     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 al-
     low 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).

LOCKS
     The vnode will be locked on entry and should remain locked	on return.

RETURN VALUES
     If	the ACL	is successfully	set, then zero is returned.  Otherwise,	an ap-
     propriate error code is returned.

ERRORS
     [EINVAL]		The ACL	type passed is invalid for this	vnode, or the
			ACL data is invalid.

     [EACCES]		The caller does	not have the appropriate privilege.

     [ENOMEM]		Sufficient memory is not available to fulfill the re-
			quest.

     [EOPNOTSUPP]	The file system	does not support VOP_SETACL().

     [ENOSPC]		The file system	is out of space.

     [EROFS]		The file system	is read-only.
