+libMemcached is an open source C/C++ client library and tools for the memcached server (http://danga.com/memcached). 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
applications by alleviating database load." `http://danga.com/memcached/ <http://danga.com/memcached/>`_
\ **libmemcached**\ is a small, thread-safe client library for the
-memcached protocol. The code has all been written with an eye to allow
+memcached protocol. The code has all been written to allow
for both web and embedded usage. It handles the work behind routing
-particular keys to specific servers that you specify (and values are
-matched based on server order as supplied by you). It implements both
-a modula and consistent method of object distribution.
+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.
+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
Nearly all functions return a \ ``memcached_return_t``\ value.
This value can be translated to a printable string with memcached_strerror(3).
-Partitioning based on keys is supported in the library. Using the key partioning
-functions it is possible to group sets of object onto servers.
+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.
\ ``memcached_st``\ structures are thread-safe, but each thread must
contain its own structure (that is, if you want to share these among
used in this library.
If you are working with GNU autotools you will want to add the following to
-your configure.ac to properly include libmemcached in your application.
+your COPYING to properly include libmemcached in your application.
PKG_CHECK_MODULES(DEPS, libmemcached >= 0.8.0)
AC_SUBST(DEPS_CFLAGS)
Hope you enjoy it!

CONSTANTS
-*********
+---------
A number of constants have been provided for in the library.
-MEMCACHED_DEFAULT_PORT
+.. c:var:: MEMCACHED_DEFAULT_PORT
The default port used by memcached(3).
-MEMCACHED_MAX_KEY
+.. c:var:: MEMCACHED_MAX_KEY
Default maximum size of a key (which includes the null pointer). Master keys
have no limit, this only applies to keys used for storage.
-MEMCACHED_MAX_KEY
+.. c:var:: MEMCACHED_MAX_KEY
Default size of key (which includes the null pointer).
-MEMCACHED_STRIDE
+.. c:var:: MEMCACHED_STRIDE
This is the "stride" used in the consistent hash used between replicas.
-MEMCACHED_MAX_HOST_LENGTH
+.. c:var:: MEMCACHED_MAX_HOST_LENGTH
Maximum allowed size of the hostname.
-
-MEMCACHED_VERSION_STRING
+.. c:var:: LIBMEMCACHED_VERSION_STRING
String value of libmemcached version such as "1.23.4"
-
-MEMCACHED_MAJOR_VERSION
+.. c:var:: LIBMEMCACHED_VERSION_HEX
- Major version value. Such as 1.23.4, would be 1
-
-
-
-MEMCACHED_MINOR_VERSION
-
- Major version value. Such as 1.23.4, would be 23
-
-
-
-MEMCACHED_MICRO_VERSION
-
- Major version value. Such as 1.23.4, would be 4
+ Hex value of the version number. "0x00048000" This can be used for comparing versions based on number.

+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(3) on a \ ``memcached_st``\ and then use the resulting cloned
structure.
