—
duplicate an ACL
LIBRARY¶
Linux Access Control Lists library (libacl, -lacl).
SYNOPSIS¶
#include
<sys/types.h>
#include <sys/acl.h>
acl_t
acl_dup

acl);
DESCRIPTION¶
The
acl_dup
()
function returns a pointer to a copy of the ACL pointed to by
acl.
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_dup
()
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
acl_dup
() function returns a value of
(acl_t)NULL
and sets errno to
the corresponding value:
