       #include <libmemcached-1.0/memcached.h>

       LIBMEMCACHED

       memcached_st *memcached(const char *string, size_t string_length)

       memcached_return_t       libmemcached_check_configuration(const       char *option_string,

       Compile and link with -lmemcached

DESCRIPTION

       Libmemcached implements a custom  language  for  configuring  and  modifying  servers.  By
       passing  in  an  option  string you can generate a memcached_st object that you can use in
       your application directly.

       --SERVER=<servername>:<optional_port>/?<optional_weight>

       Provide a servername to be used by the client. Providing a weight will cause weighting  to
       occur with all hosts with each server getting a default weight of 1.

       --SOCKET="<filepath>/?<optional_weight>"

       Provide a filepath to a UNIX socket file. Providing a weight will cause weighting to occur
       with all hosts with each server getting a default weight of 1.

       --VERIFY-KEY

       Verify that keys that are being used fit within the design of the protocol being used.

       --REMOVE_FAILED_SERVERS

       Enable the behavior MEMCACHED_BEHAVIOR_REMOVE_FAILED_SERVERS.

       --BINARY-PROTOCOL

       Force all connections to use the binary protocol.

       --BUFFER-REQUESTS

       Enable MEMCACHED_BEHAVIOR_BUFFER_REQUESTS.

       --CONFIGURE-FILE=

       Provide a configuration file to  be  used  to  load  requests.  Beware  that  by  using  a
       configuration  file  libmemcached  will  reset  memcached_st  based  on  information  only
       contained in the file.

       --CONNECT-TIMEOUT=

       Enable MEMCACHED_BEHAVIOR_CONNECT_TIMEOUT.

       --DISTRIBUTION=

       Set the distribution model used by the client.  See :manpage:`` for more details.

       --HASH=

       Set the hashing alogrthm used for placing keys on servers.

       --HASH-WITH-NAMESPACE

       When enabled the prefix key will be added to the key  when  determining  which  server  to
       store the data in.

       --NOREPLY

       Enable  "no  reply" for all calls that support this. It is highly recommended that you use
       this option with the binary protocol only.

       --NUMBER-OF-REPLICAS=

       Set the nummber of servers that keys will be replicated to.

       --RANDOMIZE-REPLICA-READ

       Select randomly the server within the replication pool to read from.

       --SORT-HOSTS

       When adding new servers always calculate their distribution based on sorted naming order.

       --SUPPORT-CAS

       See memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_SUPPORT_CAS

       --USE-UDP

       See memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_USE_UDP

       --NAMESPACE=

       A namespace is a container that provides context for keys, only other requests  that  know
       the  namespace  can  access these values. This is accomplished by prepending the namespace
       value to all keys.

   Mecached Pool Options:
       --POOL-MIN

       Initial size of pool.

       --POOL-MAX

       Maximize size of the pool.

   I/O Options:
       --TCP-NODELAY

       See memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_TCP_NODELAY

       --TCP-KEEPALIVE

       See memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_TCP_KEEPALIVE

       --RETRY-TIMEOUT=

       See memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_RETRY_TIMEOUT

       --SERVER-FAILURE-LIMIT=

       See memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_SERVER_FAILURE_LIMIT

       --SND-TIMEOUT=

       See memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_SND_TIMEOUT

       --SOCKET-RECV-SIZE=

       See memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_SOCKET_RECV_SIZE

       --SOCKET-SEND-SIZE=

       See memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_SOCKET_SEND_SIZE

       --POLL-TIMEOUT=

       That sets the value of the timeout used by :manpage: poll().

       --IO-BYTES-WATERMARK=

       --IO-KEY-PREFETCH=

       --IO-MSG-WATERMARK=

       --TCP-KEEPIDLE

       --RCV-TIMEOUT=

   Other:
       INCLUDE

       Include a file in configuration. Unlike --CONFIGURE-FILE= this will not reset memcached_st

       RESET

       Reset memcached_st and continue to process.

       END

       End configutation processing.

       ERROR

       End configutation processing and throw an error.

RETURN

       memcached() returns a pointer to the memcached_st that was created (or  initialized).   On
       an allocation failure, it returns NULL.

EXAMPLE

       const char *config_string= "--SERVER=host10.example.com --SERVER=host11.example.com --SERVER=host10.example.com"
       memcached_st *memc= memcached(config_string, strlen(config_string);
       {
        ...
       }
       memcached_free(memc);
