Example 1. Adding an item to a hash.
 
 
#include "uthash.h"
struct my_struct {
    int id;            /* we'll use this field as the key */
    char name[10];
    UT_hash_handle hh; /* makes this structure hashable */
};
struct my_struct *users = NULL;
void add_user(struct my_struct *s) {
    HASH_ADD_INT(users, id, s);
}
Example 2. Looking up an item in a hash.
 
 
struct my_struct *find_user(int user_id) {
    struct my_struct *s;
    HASH_FIND_INT(users, &user_id, s);
    return s;
}
Example 3. Deleting an item from a hash.
 
 
 For more information and examples, please see the User Guide.
void delete_user(struct my_struct *user) {
    HASH_DEL(users, user);
}
