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

NAME
     VOP_GETACL	-- retrieve access control list	for a vnode

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

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

DESCRIPTION
     This vnode	call may be used to retrieve the access	control	list (ACL)
     from a file or directory.

     Its arguments are:

     vp	   The vnode of	the file or directory.

     type  The type of ACL to retrieve.

     aclp  A pointer to	an ACL structure to receive the	ACL data.

     cred  The user credentials	to use in authorizing the request.

     td	   The thread requesting 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 al-
     low the kernel to authorize ACL retrieval 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).

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

RETURN VALUES
     If	the aclp pointer will point to a valid ACL, then zero is returned.
     Otherwise,	an appropriate error code is returned.

ERRORS
     [EINVAL]		The ACL	type passed is invalid for this	vnode.

     [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_GETACL().
