  32 DESCRIPTION
  33 ***********
  34
  35
  36 "Memcached is a high-performance, distributed memory object caching
  37 system, generic in nature, but intended for use in speeding up dynamic web
  38 applications by alleviating database load." `http://danga.com/memcached/ <http://danga.com/memcached/>`_
  39
  40 \ **libmemcached**\  is a small, thread-safe client library for the
  41 memcached protocol. The code has all been written with an eye to allow
  42 for both web and embedded usage. It handles the work behind routing
  43 particular keys to specific servers that you specify (and values are
  44 matched based on server order as supplied by you). It implements both
  45 a modula and consistent method of object distribution.
  46
  47 There are multiple implemented routing and hashing methods. See the
  48 memcached_behavior_set() manpage.
  49
  50 All operations are performed against a \ ``memcached_st``\  structure.
  51 These structures can either be dynamically allocated or statically
  52 allocated and then initialized by memcached_create(). Functions have been
  53 written in order to encapsulate the \ ``memcached_st``\ . It is not
  54 recommended that you operate directly against the structure.
  55
  56 Nearly all functions return a \ ``memcached_return_t``\  value.
  57 This value can be translated to a printable string with memcached_strerror(3).
  58
  59 Partitioning based on keys is supported in the library. Using the key partioning
  60 functions it is possible to group sets of object onto servers.
  61
  62 \ ``memcached_st``\  structures are thread-safe, but each thread must
  63 contain its own structure (that is, if you want to share these among
  64 threads you must provide your own locking). No global variables are
  65 used in this library.
  66
  67 If you are working with GNU autotools you will want to add the following to
  68 your configure.ac to properly include libmemcached in your application.

  74 Some features of the library must be enabled through memcached_behavior_set().

  80 CONSTANTS
  81 *********
  82
  83
  84 A number of constants have been provided for in the library.
  85
  86
  87 MEMCACHED_DEFAULT_PORT
  88
  89  The default port used by memcached(3).
  90
  91
  92
  93 MEMCACHED_MAX_KEY
  94
  95  Default maximum size of a key (which includes the null pointer). Master keys
  96  have no limit, this only applies to keys used for storage.
  97
  98
  99
 100 MEMCACHED_MAX_KEY
 101
 102  Default size of key (which includes the null pointer).
 103
 104
 105
 106 MEMCACHED_STRIDE
 107
 108  This is the "stride" used in the consistent hash used between replicas.
 109
 110
 111
 112 MEMCACHED_MAX_HOST_LENGTH
 113
 114  Maximum allowed size of the hostname.
 115
 116
 117
 118 MEMCACHED_VERSION_STRING
 119
 120  String value of libmemcached version such as "1.23.4"
 121
 122
 123
 124 MEMCACHED_MAJOR_VERSION
 125
 126  Major version value. Such as 1.23.4, would be 1
 127
 128
 129
 130 MEMCACHED_MINOR_VERSION
 131
 132  Major version value. Such as 1.23.4, would be 23
 133
 134
 135
 136 MEMCACHED_MICRO_VERSION
 137
 138  Major version value. Such as 1.23.4, would be 4

 143 *********************
 144 THREADS AND PROCESSES
 145 *********************
 146
 147
 148 When using threads or forked processes it is important to keep an instance
 149 of \ ``memcached_st``\  per process or thread. Without creating your own locking
 150 structures you can not share a single \ ``memcached_st``\ . You can though call
 151 memcached_quit(3) on a \ ``memcached_st``\  and then use the resulting cloned
 152 structure.
