13 The explain_ftruncate_or_die function is used to call the ftruncate(2)
14 system call. On failure an explanation will be printed to stderr,
15 obtained from explain_ftruncate(3), and then the process terminates by
16 calling exit(EXIT_FAILURE).

19 lowing example:
20 explain_ftruncate_or_die(fildes, length);

23 call.

26 call.
