The explain_closedir_or_die function
is used to call the closedir(3) system
call. On failure an explanation will be
printed to stderr,
obtained from explain_closedir(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_closedir_or_die(dir);
dir
The dir, exactly as to be passed to the closedir(3) system call.
Returns:
This function only returns on success.
On failure, prints an explanation and exits.
