The
acl_dup ();
function returns a pointer to a copy of the ACL pointed to by the argument
acl
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_free3
with the
(void*)acl_t
as an argument.
Any existing ACL pointers that refer to the ACL referred to by
acl
shall continue to refer to the ACL.
IMPLEMENTATION NOTES
Fx Ns 's
support for POSIX.1e interfaces and features is still under
development at this time.
RETURN VALUES
Upon successful completion, this function shall return a pointer to the
duplicate ACL.
Otherwise, a value of
(acl_t)NULL
shall be returned, and
errno
shall be set to indicate the error.
ERRORS
If any of the following conditions occur, the
acl_init ();
function shall return a value of
(acl_t)NULL
and set
errno
to the corresponding value:
Bq Er EINVAL
Argument
acl
does not point to a valid ACL.
Bq Er ENOMEM
The
acl_t
to be returned requires more memory than is allowed by the hardware or
system-imposed memory management constraints.
POSIX.1e is described in IEEE POSIX.1e draft 17.
Discussion
of the draft continues on the cross-platform POSIX.1e implementation
mailing list.

Fx POSIX.1e implementation

HISTORY
POSIX.1e support was introduced in
Fx 4.0 ,
and development continues.
