explain_closedir_or_die - close a directory and report errors

#include <libexplain/closedir.h>

void explain_closedir_or_die(DIR *dir);

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);
The dir, exactly as to be passed to the closedir(3) system call.
This function only returns on success. On failure, prints an explanation and exits.

closedir(3)
close a directory
explain_closedir(3)
explain closedir(3) errors
exit(2)
terminate the calling process
