  88 .SH DESCRIPTION
  89 .sp
  90 \fI\%memcached_pool()\fP is used to create a connection pool of objects you
  91 may use to remove the overhead of using memcached_clone for short lived
  92 \fBmemcached_st\fP objects. Please see \fBlibmemcached_configuration\fP for details on the format of the configuration string.
  93 .sp
  94 \fI\%memcached_pool_destroy()\fP is used to destroy the connection pool
  95 created with \fI\%memcached_pool_create()\fP and release all allocated
  96 resources. It will return the pointer to the \fBmemcached_st\fP structure
  97 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..
  98 .sp
  99 \fI\%memcached_pool_fetch()\fP is used to fetch a connection structure from the
 100 connection pool. The relative_time argument specifies if the function should
 101 block and wait for a connection structure to be available if we try
 102 to exceed the maximum size. You need to specify time in relative time.
 103 .sp
 104 \fI\%memcached_pool_release()\fP is used to return a connection structure back to the pool.
 105 .sp
 106 \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.
 107 .sp
 108 Both \fI\%memcached_pool_release()\fP and \fI\%memcached_pool_fetch()\fP are thread safe.
 109 .SH RETURN
 110 .sp
 111 \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.
 112 .sp
 113 \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).
 114 .sp
 115 \fI\%memcached_pool_release()\fP returns \fBMEMCACHED_SUCCESS\fP upon success.
 116 .sp
 117 \fI\%memcached_pool_behavior_get()\fP and \fI\%memcached_pool_behavior_get()\fP returns \fBMEMCACHED_SUCCESS\fP upon success.
 118 .sp
 119 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.
 120 .sp
 121 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.
