NAME

       acl_from_mode — create an ACL from file permission bits

LIBRARY

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

SYNOPSIS

       #include <sys/types.h>
       #include <acl/libacl.h>

       acl_t
       acl_from_mode(mode_t mode);

DESCRIPTION

       The  acl_from_mode()  function  creates  a  minimal  ACL  that  contains the three entries with tag types
       ACL_USER_OBJ, ACL_GROUP_OBJ, and ACL_OTHER, with permissions corresponding to the owner, group, and other
       permission bits of its argument mode.

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_from_mode() function returns a value of (acl_t)NULL and
       sets errno to the corresponding value:

       [ENOMEM]           The  ACL  working  storage  requires  more  memory  than is allowed by the hardware or
                          system-imposed memory management constraints.

STANDARDS

       This is a non-portable, Linux specific extension to the ACL manipulation functions defined  in  IEEE  Std
       1003.1e draft 17 (“POSIX.1e”, abandoned).
