When you get control of the system how can you get control of the machine for a longer period of time? As a white hat, has torn a hole in the opponent's line of defense, if you need to further expand the results, you need to do is latent, collect

The simple hash is to use the combination of array plus list to achieve, this hash is very simple, but the idea of hash in that.#ifndef _hash_h_#define _hash_h_typedef struct _listnode{struct _listnode *prev;struct _listnode *next;void *data;}

Defined:The hash function h takes the variable-length data block M as input, producing a fixed-length hash value h = h (m). Called M is the original image of H. Because H is a many-to-one mapping, there are multiple primitives for any given hash
