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

       The  acl_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, the acl_init() function returns a value of (acl_t)NULL and sets
       errno to the corresponding value:

       [EINVAL]           The value of count is less than zero.

       [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 (“POSIX.1e”, abandoned)
