The
acl_to_text ();
function translates the ACL pointed to by the argument
acl
into a
NULL
terminated character string. If the pointer
len_p
is not
NULL
then the function returns the length of the string (not
including the
NULL
terminator) in the location pointed to by
len_p
The format of the text string returned by
acl_to_text ();
is the long text form defined in
acl(5).
The ACL referred to by
acl
is not changed.
This function allocates any memory necessary to contain the string and
returns a pointer to the string. The caller should free any releasable
memory, when the new string is no longer required, by calling
acl_free3
with the
(void*)char
returned by
acl_to_text ();
as an argument.
RETURN VALUE
On success, this function returns a pointer to the
long text form of the ACL.
On error, a value of
(char *)NULL
is returned, and
errno
is set appropriately.
ERRORS
If any of the following conditions occur, the
acl_to_text ();
function returns a value of
(char *)NULL
and sets
errno
to the corresponding value:
Bq Er EINVAL
The argument
acl
is not a valid pointer to an ACL.
The ACL referenced by
acl
contains one or more improperly formed ACL entries, or for some other
reason cannot be translated into a text form of an ACL.
Bq Er ENOMEM
The character string to be returned requires more memory than is allowed
by the hardware or system-imposed memory management constraints.
