NAME¶
memcached - libmemcached Documentation
SYNOPSIS¶
#include <libmemcached-1.0/memcached.h>
- 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 that keys that are being used fit within the design of the protocol being
used.
Enable the behavior MEMCACHED_BEHAVIOR_REMOVE_FAILED_SERVERS.
Force all connections to use the binary protocol.
Enable MEMCACHED_BEHAVIOR_BUFFER_REQUESTS.
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.
Enable MEMCACHED_BEHAVIOR_CONNECT_TIMEOUT.
Set the distribution model used by the client. See :manpage:`` for more details.
Set the hashing alogrthm used for placing keys on servers.
When enabled the prefix key will be added to the key when determining which
server to store the data in.
Enable "no reply" for all calls that support this. It is highly
recommended that you use this option with the binary protocol only.
Set the nummber of servers that keys will be replicated to.
Select randomly the server within the replication pool to read from.
When adding new servers always calculate their distribution based on sorted
naming order.
See
memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_SUPPORT_CAS
See
memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_USE_UDP
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:¶
Initial size of pool.
Maximize size of the pool.
I/O Options:¶
See
memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_TCP_NODELAY
See
memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_TCP_KEEPALIVE
See
memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_RETRY_TIMEOUT
See
memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_SERVER_FAILURE_LIMIT
See
memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_SND_TIMEOUT
See
memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_SOCKET_RECV_SIZE
See
memcached_behavior_set(3) for MEMCACHED_BEHAVIOR_SOCKET_SEND_SIZE
That sets the value of the timeout used by :manpage:
poll().
Other:¶
Include a file in configuration. Unlike --CONFIGURE-FILE= this will not reset
memcached_st
Reset memcached_st and continue to process.
End configutation processing.
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);
