The caller should free any 50releasable memory, when the new ACL is no longer required, by calling 51.Xr acl_free 3 52with the 53.Va (void *)acl_t 54as an argument. 55.Sh IMPLEMENTATION NOTES 56.Fx Ns 's 57support for POSIX.1e interfaces and features is still under 58development at this time. 59.Sh RETURN VALUES 60Upon successful completion, the function shall return a pointer to the 61internal representation of the ACL in working storage. Otherwise, a value 62of 63.Va (acl_t)NULL 64shall be returned, and 65.Va errno 66shall be set to indicate the error. 67.Sh ERRORS 68If any of the following conditions occur, the 69.Fn acl_from_text 70function shall return a value of 71.Va (acl_t)NULL 72and set 73.Va errno 74to the corresponding value: 75.Bl -tag -width Er 76.It Bq Er EINVAL 77Argument 78.Va buf_p 79cannot be translated into an ACL. 80.It Bq Er ENOMEM 81The ACL working storage requires more memory than is allowed by the 82hardware or system-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 acl_to_text 3 , 89.Xr posix1e 3 90.Sh STANDARDS 91POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion 92of the draft continues on the cross-platform POSIX.1e implementation 93mailing list. To join this list, see the 94.Fx 95POSIX.1e implementation 96page for more information. 97.Sh HISTORY 98POSIX.1e support was introduced in 99.Fx 4.0 , 100and development continues. 101.Sh AUTHORS 102.An Robert N M Watson 103.Sh BUGS 104These features are not yet fully implemented. 105.Pp 106.Fn acl_from_text 107and 108.Fn acl_to_text 109rely on the 110.Xr getpwent 3 111library calls to manage username and uid mapping, as well as the 112.Xr getgrent 3 113library calls to manage groupname and gid mapping. These calls are not 114thread safe, and so transitively, neither are 115.Fn acl_from_text 116and 117.Fn acl_to_text . 118These functions may also interfere with stateful 119calls associated with the 120.Fn getpwent 121and 122.Fn getgrent 123calls. 124
