A pointer to the working storage is returned. The working 50storage allocated to contain the ACL is freed by a call to 51.Xr acl_free 3 . 52When the area is first allocated, it shall contain an ACL that contains 53no ACL entries. 54.Pp 55This function may cause memory to be allocated. The caller should free any 56releasable memory, when the new ACL is no longer required, by calling 57.Xr acl_free 3 58with the 59.Va (void*)acl_t 60as an argument. 61.Sh IMPLEMENTATION NOTES 62.Fx Ns 's 63support for POSIX.1e interfaces and features is still under 64development at this time. 65.Sh RETURN VALUES 66Upon successful completion, this function shall return a pointer to the 67working storage. Otherwise, a value of 68.Va (acl_t)NULL 69shall be returned, and 70.Va errno 71shall be set to indicate the error. 72.Sh ERRORS 73If any of the following conditions occur, the 74.Fn acl_init 75function shall return a value of 76.Va (acl_t)NULL 77and set 78.Va errno 79to the corresponding value: 80.Bl -tag -width Er 81.It Bq Er EINVAL 82The value of count is less than zero. 83.It Bq Er ENOMEM 84The 85.Va acl_t 86to be returned requires more memory than is allowed by the hardware or 87system-imposed memory management constraints. 88.El 89.Sh SEE ALSO 90.Xr acl 3 , 91.Xr acl_free 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.
