A pointer to the working storage is returned. The working 48storage allocated to contain the ACL is freed by a call to 49.Xr acl_free 3 . 50When the area is first allocated, it shall contain an ACL that contains 51no ACL entries. 52.Pp 53This function may cause memory to be allocated. The caller should free any 54releasable memory, when the new ACL is no longer required, by calling 55.Xr acl_free 3 56with the 57.Va (void*)acl_t 58as an argument. 59.Sh IMPLEMENTATION NOTES 60.Fx Ns 's 61support for POSIX.1e interfaces and features is still under 62development at this time. 63.Sh RETURN VALUES 64Upon successful completion, this function shall return a pointer to the 65working storage. Otherwise, a value of 66.Va (acl_t)NULL 67shall be returned, and 68.Va errno 69shall be set to indicate the error. 70.Sh ERRORS 71If any of the following conditions occur, the 72.Fn acl_init 73function shall return a value of 74.Va (acl_t)NULL 75and set 76.Va errno 77to the corresponding value: 78.Bl -tag -width Er 79.It Bq Er EINVAL 80The value of count is less than zero. 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 posix1e 3 91.Sh STANDARDS 92POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion 93of the draft continues on the cross-platform POSIX.1e implementation 94mailing list. To join this list, see the 95.Fx 96POSIX.1e implementation 97page for more information. 98.Sh HISTORY 99POSIX.1e support was introduced in 100.Fx 4.0 , 101and development continues. 102.Sh AUTHORS 103.An Robert N M Watson 104.Sh BUGS 105These features are not yet fully implemented. 106
