                                                                                       explain_fstatfs_or_die(3)

       The explain_fstatfs_or_die function is used to call the fstatfs(2) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_fstatfs(3) function, and then the process terminates
       by calling exit(EXIT_FAILURE).

       The  explain_fstatfs_on_error  function  is  used  to  call  the  fstatfs(2)  system  call. On failure an
       explanation will be printed to stderr, obtained from the explain_fstatfs(3) function, but  still  returns
       to the caller.

       fildes  The fildes, exactly as to be passed to the fstatfs(2) system call.

       data    The data, exactly as to be passed to the fstatfs(2) system call.

       The explain_fstatfs_or_die function is intended to be used in a fashion similar to the following example:
              explain_fstatfs_or_die(fildes, data);

       explain_fstatfs_or_die - get file system statistics and report errors

       The  explain_fstatfs_or_die  function  only  returns  on success, see fstatfs(2) for more information. On
       failure, prints an explanation and exits, it does not return.

       The explain_fstatfs_on_error function always returns the value return by the  wrapped  fstatfs(2)  system
       call.
