NAME
acl_init
—
initialize ACL working storage
LIBRARY
Linux Access Control Lists library (libacl, -lacl).SYNOPSIS
#include <sys/types.h>
#include <sys/acl.h>
acl_t
acl_init
(int
count);
DESCRIPTION
Theacl_init
() function allocates and initializes the
working storage for an ACL of at least count ACL
entries. The ACL created initially contains no ACL entries. A pointer to the
working storage is returned.
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_init
() 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, theacl_init
()
function returns a value of (acl_t)NULL
and sets
errno to the corresponding value:
