33 .Nd create an ACL from text
40 .Fn acl_from_text "const char *buf_p"
44 function converts the text form of an ACL referred to by
46 into the internal working structure for ACLs, appropriate for applying to
47 files or manipulating.
49 This function may cause memory to be allocated. The caller should free any
50 releasable memory, when the new ACL is no longer required, by calling
55 .Sh IMPLEMENTATION NOTES
57 support for POSIX.1e interfaces and features is still under
58 development at this time.
60 Upon successful completion, the function shall return a pointer to the
61 internal representation of the ACL in working storage. Otherwise, a value
64 shall be returned, and
66 shall be set to indicate the error.
68 If any of the following conditions occur, the
70 function shall return a value of
74 to the corresponding value:
77 Search permission is denied for a component of the path prefix, or the
78 object exists and the process does not have appropriate access rights.
82 cannot be translated into an ACL.
84 The ACL working storage requires more memory than is allowed by the
85 hardware or system-imposed memory management constraints.
94 POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion
95 of the draft continues on the cross-platform POSIX.1e implementation
96 mailing list. To join this list, see the
98 POSIX.1e implementation
99 page for more information.
101 POSIX.1e support was introduced in
103 and development continues.

107 These features are not yet fully implemented. In particular, the shipped
108 version of UFS/FFS does not support storage of additional security labels,
109 and so is unable to (easily) provide support for most of these features.

118 library calls to manage groupname and gid mapping. These calls are not
119 thread safe, and so transitively, neither are
