DESCRIPTION

13       The  explain_truncate_or_die  function  is used to call the truncate(2)
14       system call.  On failure an explanation  will  be  printed  to  stderr,
15       obtained  from  explain_truncate(3), and then the process terminates by
16       calling exit(EXIT_FAILURE).
17
18       This function is intended to be used in a fashion similar to  the  fol‐
19       lowing example:
20              explain_truncate_or_die(pathname, length);
21
22       pathname
23               The pathname, exactly as to be passed to the truncate(2) system
24               call.
25
26       length  The length, exactly as to be passed to the  truncate(2)  system
27               call.
28
29       Returns:
30               This  function  only returns on success.  On failure, prints an
31               explanation and exits.
