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.
