VOP_SETACL(9)	       FreeBSD 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
     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).

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
     appropriate error code is returned.

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

			ACL data is invalid.

     [EACCES]		The the caller does not have the appropriate privi-

			lege.

     [ENOMEM]		Sufficient memory is not available to fulfill the

			request.

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

     [ENOSPC]		The file system is out of space.

     [EROFS]		The file system is read-only.
