  11   #include <memcached.h>
  12
  13 =head1 DESCRIPTION
  14
  15 "Memcached is a high-performance, distributed memory object caching
  16 system, generic in nature, but intended for use in speeding up dynamic web
  17 applications by alleviating database load." L<http://danga.com/memcached/>
  18
  19 B<libmemcached> is a small, thread-safe client library for the
  20 memcached protocol. The code has all been written with an eye to allow
  21 for both web and embedded usage. It handles the work behind routing
  22 particular keys to specific servers that you specify (and values are
  23 matched based on server order as supplied by you). It implements both
  24 a modula and consistent method of object distribution.
  25
  26 There are multiple implemented routing and hashing methods. See the
  27 memcached_behavior_set() manpage.
  28
  29 All operations are performed against a C<memcached_st> structure.
  30 These structures can either be dynamically allocated or statically
  31 allocated and then initialized by memcached_create(). Functions have been
  32 written in order to encapsulate the C<memcached_st>. It is not
  33 recommended that you operate directly against the structure.
  34
  35 Nearly all functions return a C<memcached_return> value.
  36 This value can be translated to a printable string with memcached_strerr(3).
  37
  38 Partitioning based on keys is supported in the library. Using the key partioning
  39 functions it is possible to group sets of object onto servers.
  40
  41 C<memcached_st> structures are thread-safe, but each thread must
  42 contain its own structure (that is, if you want to share these among
  43 threads you must provide your own locking). No global variables are
  44 used in this library.
  45
  46 If you are working with GNU autotools you will want to add the following to
  47 your configure.ac to properly include libmemcached in your application.

  49 PKG_CHECK_MODULES(DEPS, libmemcached >= 0.8.0)

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

  55 Hope you enjoy it!

  57 =head1 THREADS AND PROCESSES
  58
  59 When using threads or forked processes it is important to keep an instance
  60 of C<memcached_st> per process or thread. Without creating your own locking
  61 structures you can no share a single C<memcached_st>. You can though call
  62 memcached_close(3) on a C<memcached_st> and then use the resulting cloned
  63 structure.
