Teh caller should free any 46releaseable memory, when the new ACL is no longer required, by calling 47.Xr acl_free 3 48with the 49.Va (void*)acl_t 50as an argument. 51 52Any existing ACL pointers that refer to the ACL referred to by 53.Va acl 54shall continue to refer to the ACL. 55.Sh IMPLEMENTATION NOTES 56FreeBSD's support for POSIX.1e interfaces and features is still under 57development at this time. 58.Sh RETURN VALUES 59Upon successful completion, this function shall return a pointer to the 60duplicate ACL. Otherwise, a value of 61.Va (acl_t)NULL 62shall be returned, and 63.Va errno 64shall be set to indicate the error. 65.Sh ERRORS 66If any of the following conditions occur, the 67.Fn acl_init 68function shall return a value of 69.Va (acl_t)NULL 70and set 71.Va errno 72to the corresponding value: 73.Bl -tag -width Er 74.It Bq Er EINVAL 75Argument 76.Va acl 77does not point to a valid ACL. 78.It Bq Er ENOMEM 79The 80.Va acl_t 81to be returned requires more memory than is allowed by the hardware or 82system-imposed memory management constraints. 83.El 84.Sh SEE ALSO 85.Xr acl 3 , 86.Xr acl_free 3 , 87.Xr acl_get 3 , 88.Xr posix1e 3 89.Sh STANDARDS 90POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion 91of the draft continues on the cross-platform POSIX.1e implementation 92mailing list. To join this list, see the FreeBSD POSIX.1e implementation 93page for more information. 94.Sh HISTORY 95POSIX.1e support was introduced in FreeBSD 4.0, and development continues. 96.Sh AUTHORS 97Robert N M Watson 98.Sh BUGS 99These features are not yet fully implemented. In particular, the shipped 100version of UFS/FFS does not support storage of additional security labels, 101and so is unable to (easily) provide support for most of these features. 102
