This cred setting might be used to allow the 62kernel to authorize ACL retrieval 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 will point to a valid ACL, then zero is returned. Otherwise, 76an appropriate error code is returned. 77.Sh ERRORS 78.Bl -tag -width Er 79.It Bq Er EINVAL 80The ACL type passed is invalid for this vnode 81.It Bq Er EACCES 82Permission denied 83.It Bq Er ENOMEM 84Insufficient memory available to fulfill request 85.It Bq Er EOPNOTSUPP 86The file system does not support VOP_GETACL 87.El 88.Sh SEE ALSO 89.Xr acl 9 , 90.Xr vnode 9 , 91.Xr VOP_ACLCHECK 9 , 92.Xr VOP_SETACL 9 93.Sh AUTHORS 94This man page was written by 95.An Robert Watson . 96
