NAME

       explain_ftruncate_or_die - truncate a file and report errors

SYNOPSIS

       #include <libexplain/ftruncate.h>
       void explain_ftruncate_or_die(int fildes, long long length);

DESCRIPTION

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

       This function is intended to be  used  in  a  fashion  similar  to  the
       following example:
              explain_ftruncate_or_die(fildes, length);

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

       length  The length, exactly as to be passed to the ftruncate(2)  system
               call.

       Returns:
               This  function  only returns on success.  On failure, prints an
               explanation and exits.
