acl_copy_int(3) -- Linux man page
NAME
acl_copy_int
- copy an ACL from external to internal representation
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
In sys/types.h
In sys/acl.h
Ft acl_t
Fn acl_copy_int const void *buf_p
DESCRIPTION
The
Fn acl_copy_int
function copies an exportable, contiguous, persistent form of an ACL, pointed to by
buf_p
to the internal representation.
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
Fn acl_copy_int
as an argument.
RETURN VALUE
Upon success,
the
Fn acl_copy_int
function returns a pointer that references the ACL in 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
Fn acl_copy_int
function returns a value of
(acl_t)NULL
and sets
errno
to the corresponding value:
- Bq Er EINVAL
-
The buffer pointed to by the argument
buf_p
does not contain a valid external form ACL.
- Bq Er ENOMEM
-
The ACL working storage requires more memory than is allowed by the hardware or system-imposed memory management constraints.
STANDARDS
IEEE Std 1003.1e draft 17 (lqPOSIX.1erq, abandoned)
