Please see \fBlibmemcached_configuration\fP for details on the format of the configuration string. .sp \fI\%memcached_pool_destroy()\fP is used to destroy the connection pool created with \fI\%memcached_pool_create()\fP and release all allocated resources. It will return the pointer to the \fBmemcached_st\fP structure passed as an argument to \fI\%memcached_pool_create()\fP, and returns the ownership of the pointer to the caller when created with \fI\%memcached_pool_create()\fP, otherwise NULL is returned.. .sp \fI\%memcached_pool_fetch()\fP is used to fetch a connection structure from the connection pool. The relative_time argument specifies if the function should block and wait for a connection structure to be available if we try to exceed the maximum size. You need to specify time in relative time. .sp \fI\%memcached_pool_release()\fP is used to return a connection structure back to the pool. .sp \fI\%memcached_pool_behavior_get()\fP and \fI\%memcached_pool_behavior_set()\fP is used to get/set behavior flags on all connections in the pool. .sp Both \fI\%memcached_pool_release()\fP and \fI\%memcached_pool_fetch()\fP are thread safe. .SH RETURN .sp \fI\%memcached_pool_destroy()\fP returns the pointer (and ownership) to the \fBmemcached_st\fP structure used to create the pool. If connections are in use it returns NULL. .sp \fI\%memcached_pool_pop()\fP returns a pointer to a \fBmemcached_st\fP structure from the pool (or NULL if an allocation cannot be satisfied). .sp \fI\%memcached_pool_release()\fP returns \fBMEMCACHED_SUCCESS\fP upon success. .sp \fI\%memcached_pool_behavior_get()\fP and \fI\%memcached_pool_behavior_get()\fP returns \fBMEMCACHED_SUCCESS\fP upon success. .sp If any methods returns MEMCACHED_IN_PROGRESS then a lock on the pool could not be obtained. If any of the parameters passed to any of these functions is invalid, MEMCACHED_INVALID_ARGUMENTS will be returned. .sp memcached_pool_fetch may return MEMCACHED_TIMEOUT if a timeout occurs while waiting for a free memcached_st. MEMCACHED_NOTFOUND if no memcached_st was available. .SH HOME .sp To find out more information please check: \fI\%http://libmemcached.org/\fP .SH AUTHOR .sp Brian Aker, <\fI\%brian@tangent.org\fP> .sp Trond Norbye, <\fI\%trond.norbye@gmail.com\fP> .SH SEE ALSO .sp \fImemcached(1)\fP \fIlibmemcached(3)\fP \fImemcached_strerror(3)\fP \fIlibmemcached_configuration(3)\fP .SH AUTHOR Brian Aker .SH COPYRIGHT 2011-2013, Brian Aker DataDifferential, http://datadifferential.com/ .\" Generated by docutils manpage writer. .
