acl_from_text(3) -- Linux man page
NAME
acl_from_text
- create an ACL from text
LIBRARY
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS
In sys/types.h
In sys/acl.h
Ft acl_t
Fn acl_from_text const char *buf_p
DESCRIPTION
The
Fn acl_from_text
function converts the text form of the ACL referred to by
buf_p
into the internal form of an ACL and returns a pointer to the working storage
that contains the ACL. The
Fn acl_from_text
function accepts as input the long text form and short text form of an ACL as described in
acl(5).
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_from_text
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
Fn acl_from_text
function returns a value of
(acl_t)NULL
and sets
errno
to the corresponding value:
- Bq Er EINVAL
-
The argument
buf_p
cannot be translated into 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.
STANDARDS
IEEE Std 1003.1e draft 17 (lqPOSIX.1erq, abandoned)
