34 .Nd create an ACL from text
41 .Fn acl_from_text "const char *buf_p"
45 function converts the text form of an ACL referred to by
47 into the internal working structure for ACLs, appropriate for applying to
48 files or manipulating.
50 This function may cause memory to be allocated. The caller should free any
51 releasable memory, when the new ACL is no longer required, by calling
56 .Sh IMPLEMENTATION NOTES
58 support for POSIX.1e interfaces and features is still under
59 development at this time.
61 Upon successful completion, the function shall return a pointer to the
62 internal representation of the ACL in working storage. Otherwise, a value
65 shall be returned, and
67 shall be set to indicate the error.
69 If any of the following conditions occur, the
71 function shall return a value of
75 to the corresponding value:
78 Search permission is denied for a component of the path prefix, or the
79 object exists and the process does not have appropriate access rights.
83 cannot be translated into an ACL.
85 The ACL working storage requires more memory than is allowed by the
86 hardware or system-imposed memory management constraints.
95 POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion
96 of the draft continues on the cross-platform POSIX.1e implementation
97 mailing list. To join this list, see the
99 POSIX.1e implementation
100 page for more information.
102 POSIX.1e support was introduced in
104 and development continues.

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

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