7 C Client Library for memcached (libmemcached, -lmemcached)

15 memcached_behavior flag);
18 memcached_behavior_set (memcached_st *ptr,
19 memcached_behavior flag,
24 libmemcached(3) behavior can be modified by use memcached_behavior_set().
25 Default behavior is the library strives to be quick and accurate. Some
26 behavior, while being faster, can also result in not entirely accurate
27 behavior (for instance, memcached_set() will always respond with
28 C<MEMCACHED_SUCCESS>).
30 memcached_behavior_get() takes a behavior flag and returns whether or not
31 that behavior is currently enabled in the client.
33 memcached_behavior_set() changes the value of a particular option of the
34 client. It takes both a flag (listed below) and a value. For simple on or
35 off options you just need to pass in a value of 1. Calls to
36 memcached_behavior_set() will flush and reset all connections.
40 =item MEMCACHED_BEHAVIOR_NO_BLOCK
42 Causes libmemcached(3) to use asychronous IO. This is the fastest transport
45 =item MEMCACHED_BEHAVIOR_TCP_NODELAY
47 Turns on the no-delay feature for connecting sockets (may be faster in some
50 =item MEMCACHED_BEHAVIOR_HASH
52 Makes the default hashing algorithm for keys use MD5. The value can be set to either MEMCACHED_HASH_DEFAULT, MEMCACHED_HASH_MD5, MEMCACHED_HASH_CRC, MEMCACHED_HASH_FNV1_64, MEMCACHED_HASH_FNV1A_64, MEMCACHED_HASH_FNV1_32, MEMCACHED_HASH_FNV1A_32, MEMCACHED_HASH_KETAMA. The behavior for all hashes but MEMCACHED_HASH_DEFAULT is identitical to the Java driver written by Dustin Sallings.
54 =item MEMCACHED_BEHAVIOR_CACHE_LOOKUPS
56 Memcached can cache named lookups so that DNS lookups are made only once.
62 memcached_behavior_get() returns either the current value of the get, or 0
63 or 1 on simple flag behaviors (1 being enabled). memcached_behavior_set()
64 returns whether or not the behavior was enabled.
