• /server -> server program related sources
• /client -> client program related sources
• /common -> common inclusions
• /util -> common utilization
• /build -> target build directory

Code out your /server/server.c and /client/client.c, then

$ make

Test your /build/server and build/client.

1. Use pthread_t threads[10] array and bool *thread_sum array to record the pthread
2. Once server accept the client, the server use pthread_create to carry out the multi-thread.
3. If Clients are up to 10, the server will not accept new client.
4. Use pthread_mutex_lock and pthread_mutex_unlock to avoid race condition.

typedef struct HashNode
{
    struct HashNode* next;
    char *key;
    char *value;
} HashNode;

1. Use Hash Table as the DataBase. a linked list array (size = 26)
2. int Hashing (char* Key); : Use Key to create Hash value (0-25)
3. HashNode* HashNode_Create(char *Key, char *Value); Create a Link-list Node
4. HashNode* HashNode_Insert(HashNode* Root, char* Key,char* Value); : Save K-V pair to Hash Table (as a linked list).
5. HashNode* HashNode_Search(HashNode* Root,char *Key); : Search the Key and Return Value.
6. HashNode* HashNode_Delete(HashNode* Root,char *Key); : Delete the K-V pair.
