Syntax

cn_map_rtraverse(CN_MAP map, CNM_ITERATOR * iterator)

Description

Loop Shorthand which traverses through all nodes in map in reverse order using iterator. In the loop, you may access iterator to grab all key/value pairs. It is equivalent to:

for (cn_map_rbegin(map, iterator); !cn_map_at_rend(map, iterator); cn_map_prev(map, iterator))

Return Value

Examples

Basic Usage

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#include "cn_cmp.h"
#include "cn_map.h"

main() {
	CN_MAP map = cn_map_init(char, int, cn_cmp_char);

	char key;
	int  value;

	//Put in a-z with 0-25 in as key/value pairs.
	for (key = 'a', value = 0; key <= 'z'; key++, value++) {
		cn_map_insert(map, &key, &value);
	}

	//Iterate through
	CNM_ITERATOR it;

	cn_map_rtraverse(map, &it) {
		printf(
			"%c -> %d\n",
			cn_map_iterator_key  (&it, char),
			cn_map_iterator_value(&it, int)
		);
	}
