NAME

4     acl_init — initialize ACL working storage
5

LIBRARY

7     Linux Access Control Lists library (libacl, -lacl).
8

SYNOPSIS

10     #include <sys/types.h>
11     #include <sys/acl.h>
12
13     acl_t
14     acl_init(int count);
15

DESCRIPTION

17     The acl_init() function allocates and initializes the working storage for
18     an ACL of at least count ACL entries.  The ACL created initially contains
19     no ACL entries.  A pointer to the working storage is returned.
20
21     This function may cause memory to be allocated.  The caller should free
22     any releasable memory, when the new ACL is no longer required, by calling
23     acl_free(3) with the (void*)acl_t returned by acl_init() as an argument.
24

RETURN VALUE

26     On success, this function returns a pointer to the working storage.  On
27     error, a value of (acl_t)NULL is returned, and errno is set appropri‐
28     ately.
29

ERRORS

31     If any of the following conditions occur, the acl_init() function returns
32     a value of (acl_t)NULL and sets errno to the corresponding value:
33
34     [EINVAL]           The value of count is less than zero.
35
36     [ENOMEM]           The acl_t to be returned requires more memory than is
37                        allowed by the hardware or system-imposed memory man‐
38                        agement constraints.
