LIBMEMCACHED_CHECK_CONFIGURATION(3)

NAME
libmemcached_check_configuration - libmemcached Documentation

SYNOPSIS

#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, size_t length, char *error_buffer, size_t error_buffer_size)

    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

    Please see 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=

    Please see 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);
