The caller should free any 52releasable memory, when the new ACL is no longer required, by calling 53.Xr acl_free 3 54with the 55.Va (void *)acl_t 56as an argument. 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, the function shall return a pointer to the 63internal representation of the ACL in working storage. Otherwise, a value 64of 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_from_text 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 buf_p 81cannot be translated into an ACL. 82.It Bq Er ENOMEM 83The ACL working storage requires more memory than is allowed by the 84hardware or system-imposed memory management constraints. 85.El 86.Sh SEE ALSO 87.Xr acl 3 , 88.Xr acl_free 3 , 89.Xr acl_get 3 , 90.Xr acl_to_text 3 , 91.Xr posix1e 3 92.Sh STANDARDS 93POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion 94of the draft continues on the cross-platform POSIX.1e implementation 95mailing list. To join this list, see the 96.Fx 97POSIX.1e implementation 98page for more information. 99.Sh HISTORY 100POSIX.1e support was introduced in 101.Fx 4.0 , 102and development continues. 103.Sh AUTHORS 104.An Robert N M Watson 105.Sh BUGS 106The 107.Fn acl_from_text 108and 109.Fn acl_to_text 110functions 111rely on the 112.Xr getpwent 3 113library calls to manage username and uid mapping, as well as the 114.Xr getgrent 3 115library calls to manage groupname and gid mapping. These calls are not 116thread safe, and so transitively, neither are 117.Fn acl_from_text 118and 119.Fn acl_to_text . 120These functions may also interfere with stateful 121calls associated with the 122.Fn getpwent 123and 124.Fn getgrent 125calls. 126
