For hash table operations, you may use uthash. \"uthash.h\" is included by default. Below are some examples:

\r\n\r\n

1. Adding an item to a hash.\r\n

\r\nstruct hash_entry {\r\n    int id;            /* we'll use this field as the key */\r\n    char name[10];\r\n    UT_hash_handle hh; /* makes this structure hashable */\r\n};\r\n\r\nstruct hash_entry *users = NULL;\r\n\r\nvoid add_user(struct hash_entry *s) {\r\n    HASH_ADD_INT(users, id, s);\r\n}\r\n

\r\n

\r\n\r\n

2. Looking up an item in a hash:\r\n

\r\nstruct hash_entry *find_user(int user_id) {\r\n    struct hash_entry *s;\r\n    HASH_FIND_INT(users, &user_id, s);\r\n    return s;\r\n}\r\n

\r\n

\r\n\r\n

3. Deleting an item in a hash:\r\n

\r\nvoid delete_user(struct hash_entry *user) {\r\n    HASH_DEL(users, user);  \r\n}\r\n
