SYNOPSIS

9       #include <libexplain/acl_get_fd.h>
10       acl_t explain_acl_get_fd_or_die(int fildes);
11       acl_t explain_acl_get_fd_on_error(int fildes);

DESCRIPTION

14       The   explain_acl_get_fd_or_die   function   is   used   to   call  the
15       acl_get_fd(3) system call. On failure an explanation will be printed to
16       stderr,  obtained from the explain_acl_get_fd(3) function, and then the
17       process terminates by calling exit(EXIT_FAILURE).
18
19       The  explain_acl_get_fd_on_error  function  is   used   to   call   the
20       acl_get_fd(3) system call. On failure an explanation will be printed to
21       stderr, obtained from the  explain_acl_get_fd(3)  function,  but  still
22       returns to the caller.
23
24       fildes  The fildes, exactly as to be passed to the acl_get_fd(3) system
25               call.

RETURN VALUE

28       The explain_acl_get_fd_or_die function only  returns  on  success,  see
29       acl_get_fd(3)  for  more information. On failure, prints an explanation
30       and exits, it does not return.
31
32       The  explain_acl_get_fd_on_error  function  always  returns  the  value
33       return by the wrapped acl_get_fd(3) system call.
34

EXAMPLE

36       The  explain_acl_get_fd_or_die  function  is  intended  to be used in a
37       fashion similar to the following example:
38              explain_acl_get_fd_or_die(fildes);
