The
acl_dup ();
function returns a pointer to a copy of the ACL pointed to by
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
returned by
acl_dup ();
as an argument.
RETURN VALUE
On success, this function returns a pointer to the
working storage. On error, a value of
(acl_t)NULL
is returned, and
errno
is set appropriately.
ERRORS
If any of the following conditions occur, the
acl_dup ();
function returns a value of
(acl_t)NULL
and sets
errno
to the corresponding value:
Bq Er EINVAL
The argument
acl
is not a valid pointer to an 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.
