ACL_COPY_INT(3) | Library Functions Manual | ACL_COPY_INT(3) |
NAME¶
acl_copy_int
—
copy an ACL from external to internal
representation
LIBRARY¶
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS¶
#include
<sys/types.h>
#include <sys/acl.h>
acl_t
acl_copy_int
(const
void *buf_p);
DESCRIPTION¶
The
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_free(3) with the
(void*)acl_t returned by
acl_copy_int
()
as an argument.
RETURN VALUE¶
Upon success, the 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
acl_copy_int
() function returns a value of
(acl_t)NULL
and sets errno to
the corresponding value:
STANDARDS¶
IEEE Std 1003.1e draft 17 (“POSIX.1e”, abandoned)
