The caller should free any 48releasable memory, when the new ACL is no longer required, by calling 49.Xr acl_free 3 50with the 51.Va (void*)acl_t 52as an argument. 53.Pp 54Any existing ACL pointers that refer to the ACL referred to by 55.Va acl 56shall continue to refer to the ACL. 57.Sh IMPLEMENTATION NOTES 58.Fx Ns 's 59support for POSIX.1e interfaces and features is still under 60development at this time. 61.Sh RETURN VALUES 62Upon successful completion, this function shall return a pointer to the 63duplicate ACL. Otherwise, a value of 64.Va (acl_t)NULL 65shall be returned, and 66.Va errno 67shall be set to indicate the error. 68.Sh ERRORS 69If any of the following conditions occur, the 70.Fn acl_init 71function shall return a value of 72.Va (acl_t)NULL 73and set 74.Va errno 75to the corresponding value: 76.Bl -tag -width Er 77.It Bq Er EINVAL 78Argument 79.Va acl 80does not point to a valid ACL. 81.It Bq Er ENOMEM 82The 83.Va acl_t 84to be returned requires more memory than is allowed by the hardware or 85system-imposed memory management constraints. 86.El 87.Sh SEE ALSO 88.Xr acl 3 , 89.Xr acl_free 3 , 90.Xr acl_get 3 , 91.Xr posix1e 3 92.Sh STANDARDS 93POSIX.1e is described in IEEE POSIX.1e draft 17.
