LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
n sys/types.h
n sys/acl.h
DESCRIPTION
The
function translates the ACL pointed to by the argument
into a
terminated character string. If the pointer
is not
then the function returns the length of the string (not
including the
terminator) in the location pointed to by
The format of the text string returned by
is the long text form defined in
acl(5)
The ACL referred to by
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_free(3)
with the
returned by
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
is returned, and
is set appropriately.
ERRORS
If any of the following conditions occur, the
function returns a value of
and sets
to the corresponding value:
- EINVAL
The argument
is not a valid pointer to an ACL.
The ACL referenced by
contains one or more improperly formed ACL entries, or for some other
reason cannot be translated into a text form of an ACL.
ENOMEM
The character string to be returned requires more memory than is allowed
by the hardware or system-imposed memory management constraints.
