ACL_INIT(3)              Library Functions Manual            ACL_INIT(3)

NAME         top

       acl_init — initialize ACL working storage

LIBRARY         top

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

SYNOPSIS         top

       <sys/types.h> <sys/acl.h> acl_t acl_init(int count)

DESCRIPTION         top

       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         top

       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         top

       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         top

       IEEE Std 1003.1e draft 17 (“POSIX.1e”, abandoned)
