#define foreach (  map, ptr   )

Value: for (ptr = (typeof(ptr))_stp_map_start(map); ptr; \ ptr = (typeof(ptr))_stp_map_iter (map, (struct map_node *)ptr)) Loop through all elements of a map. Parameters: map  ptr  pointer to a map_node_stat, map_node_int64 or map_node_str Example: /* example showing how to print all the stats in a map using foreach() */ struct map_node_stat *ptr; foreach (map, ptr) printf ("map[%s,%ld] = [c=%lld s=%lld min=%lld max=%lld]\n", key1str(ptr), key2int(ptr), ptr->stats.count, ptr->stats.sum, ptr->stats.min, ptr->stats.max); Definition at line 149 of file map.h.
