NAME

       libmemcached - C/C++ Client Library for memcached

SYNOPSIS

       #include <libmemcached/memcached.h>
              Compile and link with -lmemcached

                                                         ----

       libmemcached   is   an  open  source  C/C++  client  library  and  tools  for  the  memcached  server  (‐
       http://memcached.org/). It has been designed to be light on memory usage, thread safe, and  provide  full
       access to server side methods.

       libmemcached  was  designed  to  provide  the  greatest  number  of options to use Memcached. Some of the
       features provided:

       1. Asynchronous and Synchronous Transport Support.

       2. Consistent Hashing and Distribution.

       3. Tunable Hashing algorithm to match keys.

       4. Access to large object support.

       5. Local replication.

       6. A complete reference guide and documentation to the API.

       7. Tools to Manage your Memcached networks.

DESCRIPTION

       "Memcached is a high-performance, distributed memory  object  caching  system,  generic  in  nature,  but
       intended   for   use   in   speeding   up   dynamic  web  applications  by  alleviating  database  load."
       http://memcached.org/

       libmemcached is a small, thread-safe client library for the memcached protocol. The  code  has  all  been
       written  to  allow for both web and embedded usage. It handles the work behind routing individual keys to
       specific servers specified by the developer (and values are matched based on server order as supplied  by
       the user). It implements a modular and consistent method of object distribution.

       There  are multiple implemented routing and hashing methods. See the memcached_behavior_set() manpage for
       more information.

       All operations are performed against a memcached_st structure. These structures can either be dynamically
       allocated or statically allocated and then initialized by memcached_create(). Functions have been written
       in order to encapsulate the memcached_st. It is not recommended that you  operate  directly  against  the
       structure.

       Nearly  all  functions  return  a  memcached_return_t  value. This value can be translated to a printable
       string with memcached_strerror().

       Objects are stored on servers by hashing keys. The hash value maps the key to a  particular  server.  All
       clients  understand  how this hashing works, so it is possibly to reliably both push data to a server and
       retrieve data from a server.

       Group keys can be optionally used to group sets of objects with servers.

       Namespaces are supported, and can be used to partition caches so that multiple applications can  use  the
       same memcached servers.

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

THREADS AND PROCESSES

       No global variables are used in this library.

       memcached_st  structures  are  thread-safe, but when using threads or forked processes it is important to
       keep one instance of memcached_st per process or thread. Without creating your own locking structures you
       can not share a single memcached_st. However, you can call memcached_quit() on a  memcached_st  and  then
       use the resulting cloned structure.

SYSTEMTAP

       libmemcached can be built to support Systemtap on Linux when enabled at compile time.

       Please see stap(1) and dtrace(1) for more information about Systemtap.
