NAME

       explain_telldir_or_die - current location in directory and report errors

SYNOPSIS

       #include <libexplain/telldir.h>
       off_t explain_telldir_or_die(DIR *dir);
       off_t explain_telldir_on_error(DIR *dir);

DESCRIPTION

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

       The  explain_telldir_on_error  function  is  used  to  call the telldir(3) system call. On
       failure an explanation will be printed to stderr,  obtained  from  the  explain_telldir(3)
       function, but still returns to the caller.

       dir     The dir, exactly as to be passed to the telldir(3) system call.

RETURN VALUE

       The  explain_telldir_or_die  function  only  returns  on  success, see telldir(3) for more
       information. On failure, prints an explanation and exits, it does not return.

       The explain_telldir_on_error function always returns  the  value  return  by  the  wrapped
       telldir(3) system call.

EXAMPLE

       The  explain_telldir_or_die  function  is  intended to be used in a fashion similar to the
       following example:
              off_t result = explain_telldir_or_die(dir);
