NAME
       explain_fstatvfs_or_die - get file system statistics and report errors

SYNOPSIS
       #include <libexplain/fstatvfs.h>
       void explain_fstatvfs_or_die(int fildes, struct statvfs *data);
       int explain_fstatvfs_on_error(int fildes, struct statvfs *data);

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

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

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

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

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

       The explain_fstatvfs_on_error function always returns the value return by the wrapped fstatvfs(2) system call.

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