       void memcached_free(memcached_st *ptr)

              Parameters
                     ptr  --  pointer  to initialized memcached_st struct to destroy and possibly
                     free

       memcached_st *memcached_clone(memcached_st *destination, memcached_st *source)

              Parameters

                     • destination -- pointer  to  user-allocated  memcached_st  struct  or  null
                       pointer

                     • source -- pointer to initialized memcached_st struct to copy from

              Returns
                     pointer to newly initialized destination, copied from source

       void memcached_servers_reset(memcached_st *ptr)

              Parameters
                     ptr -- pointer to initialized memcached_st struct

DESCRIPTION

       memcached_create()  is  used  to create a memcached_st structure that will then be used by
       other libmemcached functions to communicate with the server.  You  should  either  pass  a
       statically declared memcached_st to memcached_create() or a NULL. If a NULL passed in then
       a structure is allocated for you.

       Please note, when you write new application use memcached() over memcached_create().

       memcached_clone() is similar to memcached_create() but it copies the defaults and list  of
       servers  from  the source memcached_st pointer. If you pass a null as the argument for the
       source to clone, it is the same as  a  call  to  memcached_create().  If  the  destination
       argument is NULL a memcached_st will be allocated for you.

       memcached_servers_reset() allows you to zero out the list of servers that the memcached_st
       has.

       To clean up memory associated  with  a  memcached_st  structure  you  should  pass  it  to
       memcached_free()  when you are finished using it. memcached_free() is the only way to make
       sure all memory is deallocated when you finish using the structure.

       You may wish to avoid using memcached_create() or memcached_clone()  with  a  stack  based
       allocation.  The  most  common  issues  related  to  ABI  safety  involve  heap  allocated
       structures.

RETURN VALUE

       memcached_create()  returns  a  pointer  to  the  memcached_st  that   was   created   (or
       initialized). On an allocation failure, it returns NULL.

       memcached_clone() returns a pointer to the memcached_st that was created (or initialized).
       On an allocation failure, it returns NULL.
