libmemcached LIBMEMCACHED_EXAMPLES(3libmemcached) NAME libmemcached_examples - libmemcached Documentation Examples for libmemcached DESCRIPTION For full examples, test cases are found in tests/*.c in the main dis- tribution. These are always up to date, and are used for each test run of the library. CONNECTING TO SERVERS const char *config_string= "--SERVER=host10.example.com --SERVER=host11.example.com --SERVER=host10.example.com" memcached_st *memc= memcached(config_string, strlen(config_string); { ... } memcached_free(memc); In the above code you create a memcached_st object with three server by making use of memcached_create(). CREATING A POOL OF SERVERS Creating a pool of Servers: const char *config_string= "--SERVER=host10.example.com --SERVER=host11.example.com --SERVER=host10.example.com"; memcached_pool_st* pool= memcached_pool(config_string, strlen(config_string)); memcached_return_t rc; memcached_st *memc= memcached_pool_pop(pool, false, &rc); .... do work /* Release the memc_ptr that was pulled from the pool */ memcached_pool_push(pool, memc); /* Destroy the pool. */ memcached_pool_destroy(pool); In the above code you create a memcached_pool_st object with three server by making use of memcached_pool(). When memcached_pool_destroy() all memory will be released that is asso- ciated with the pool. ADDING A VALUE TO THE SERVER Adding a value to the Server: char *key= "foo"; char *value= "value"; memcached_return_t rc= memcached_set(memc, key, strlen(key), value, value_length, (time_t)0, (uint32_t)0); if (rc != MEMCACHED_SUCCESS) { ... // handle failure } It is best practice to always look at the return value of any opera- tion. FETCHING MULTIPLE VALUES memcached_return_t rc; char *keys[]= {"fudge", "son", "food"}; size_t key_length[]= {5, 3, 4}; unsigned int x; uint32_t flags; char return_key[MEMCACHED_MAX_KEY]; size_t return_key_length; char *return_value; size_t return_value_length; rc= memcached_mget(memc, keys, key_length, 3); x= 0; while ((return_value= memcached_fetch(memc, return_key, &return_key_length, &return_value_length, &flags, &rc))) { free(return_value); x++; } Notice that you freed values returned from memcached_fetch(). The define MEMCACHED_MAX_KEY is provided for usage.
