The caller should free any 49releasable memory, when the new ACL is no longer required, by calling 50.Xr acl_free 3 51with the 52.Va (void*)acl_t 53as an argument. 54.Pp 55Any existing ACL pointers that refer to the ACL referred to by 56.Va acl 57shall continue to refer to the ACL. 58.Sh IMPLEMENTATION NOTES 59.Dx Ns 's 60support for POSIX.1e interfaces and features is still under 61development at this time. 62.Sh RETURN VALUES 63Upon successful completion, this function shall return a pointer to the 64duplicate ACL. Otherwise, a value of 65.Va (acl_t)NULL 66shall be returned, and 67.Va errno 68shall be set to indicate the error. 69.Sh ERRORS 70If any of the following conditions occur, the 71.Fn acl_init 72function shall return a value of 73.Va (acl_t)NULL 74and set 75.Va errno 76to the corresponding value: 77.Bl -tag -width Er 78.It Bq Er EINVAL 79Argument 80.Va acl 81does not point to a valid ACL. 82.It Bq Er ENOMEM 83The 84.Va acl_t 85to be returned requires more memory than is allowed by the hardware or 86system-imposed memory management constraints. 87.El 88.Sh SEE ALSO 89.Xr acl 3 , 90.Xr acl_free 3 , 91.Xr acl_get 3 , 92.Xr posix1e 3 93.Sh STANDARDS 94POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion 95of the draft continues on the cross-platform POSIX.1e implementation 96mailing list. To join this list, see the 97.Fx 98POSIX.1e implementation 99page for more information. 100.Sh HISTORY 101POSIX.1e support was introduced in 102.Fx 4.0 , 103and development continues. 104.Sh AUTHORS 105.An Robert N M Watson 106.Sh BUGS 107These features are not yet fully implemented. In particular, the shipped 108version of UFS/FFS does not support storage of additional security labels, 109and so is unable to (easily) provide support for most of these features. 110
