create an ACL from text
Standard C Library (libc, -lc)
() function converts the text form of an ACL referred to by
into the internal working structure for ACLs, appropriate for applying to files or manipulating.
This function may cause memory to be allocated. The caller should free any releasable memory, when the new ACL is no longer required, by calling acl_free(3) with the (void *)acl_t as an argument.
FreeBSD's support for POSIX.1e interfaces and features is still under development at this time.
RETURN VALUES Upon successful completion, the function shall return a pointer to the internal representation of the ACL in working storage. Otherwise, a value of
(acl_t)NULL shall be returned, and
errno shall be set to indicate the error.
If any of the following conditions occur, the
() function shall return a value of
to the corresponding value:
buf_p cannot be translated into an ACL.
The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.
STANDARDS POSIX.1e is described in IEEE POSIX.1e draft 17. Discussion of the draft continues on the cross-platform POSIX.1e implementation mailing list. To join this list, see the
FreeBSD POSIX.1e implementation page for more information.
HISTORY POSIX.1e support was introduced in
FreeBSD 4.0, and development continues.
() functions rely on the
library calls to manage username and uid mapping, as well as the
library calls to manage groupname and gid mapping. These calls are not thread safe, and so transitively, neither are
(). These functions may also interfere with stateful calls associated with the
