.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\fImemcached_pool_create()\fR is used to create a connection pool of objects you
may use to remove the overhead of using memcached_clone for short
lived \f(CW\*(C`memcached_st\*(C'\fR objects. The mmc argument should be an
initialised \f(CW\*(C`memcached_st\*(C'\fR structure, and a successfull invocation of
memcached_pool_create takes full ownership of the variable (until it
is released by memcached_pool_destroy). The \f(CW\*(C`initial\*(C'\fR argument
specifies the initial size of the connection pool, and the \f(CW\*(C`max\*(C'\fR
argument specifies the maximum size the connection pool should grow
to. Please note that the library will allocate a fixed size buffer
scaled to the max size of the connection pool, so you should not pass
\&\s-1MAXINT\s0 or some other large number here.
.PP
\&\fImemcached_pool_destroy()\fR is used to destroy the connection pool
created with \fImemcached_pool_create()\fR and release all allocated
resources. It will return the pointer to the \f(CW\*(C`memcached_st\*(C'\fR structure
passed as an argument to \fImemcached_pool_create()\fR, and returns the
ownership of the pointer to the caller.
.PP
\&\fImemcached_pool_pop()\fR is used to grab a connection structure from the
connection pool. The block argument specifies if the function should
block and wait for a connection structure to be available if we try
to exceed the maximum size.
.PP
\&\fImemcached_pool_push()\fR is used to return a connection structure back to the pool.
.PP
\&\fImemcached_pool_behavior_set()\fR and \fImemcached_pool_behagior_get()\fR is
used to get/set behavior flags on all connections in the pool.
.SH "RETURN"
.IX Header "RETURN"
\&\fImemcached_pool_create()\fR returns a pointer to the newly created
memcached_pool_st structure. On an allocation failure, it returns
\&\s-1NULL\s0.
.PP
\&\fImemcached_pool_destroy()\fR returns the pointer (and ownership) to the
memcached_st structure used to create the pool. If connections are in
use it returns \s-1NULL\s0.
.PP
\&\fImemcached_pool_pop()\fR returns a pointer to a memcached_st structure
from the pool (or \s-1NULL\s0 if an allocation cannot be satisfied).
.PP
\&\fImemcached_pool_push()\fR returns \s-1MEMCACHED_SUCCESS\s0 upon success.
.PP
\&\fImemcached_pool_behavior_get()\fR and \fImemcached_pool_behavior_get()\fR
returns \s-1MEMCACHED_SUCCESS\s0 upon success.
