This cred setting might be used to allow the kernel to authorize ACL retrieval that the active process might not be permitted to do. .Pp 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 .Xr acl 9 . .Sh LOCKS No locks are required to call this vnode method, and any locks held on entry will be held on exit. .Sh RETURN VALUES If the .Fa aclp pointer will point to a valid ACL, then zero is returned. Otherwise, an appropriate error code is returned. .Sh ERRORS .Bl -tag -width Er .It Bq Er EINVAL The ACL type passed is invalid for this vnode .It Bq Er EACCES Permission denied .It Bq Er ENOMEM Insufficient memory available to fulfill request .It Bq Er EOPNOTSUPP The file system does not support .Fn VOP_GETACL .El .Sh SEE ALSO .Xr acl 9 , .Xr vnode 9 , .Xr VOP_ACLCHECK 9 , .Xr VOP_SETACL 9 .Sh AUTHORS This man page was written by .An Robert Watson .
