SYNOPSIS

       #include <libmemcached/memcached.h>
              Compile and link with -lmemcached

       typedef struct memcached_st memcached_st

       memcached_st *memcached_create(memcached_st *ptr)

              Parameters
                     ptr -- pointer to user-allocated memcached_st struct or null pointer

              Returns
                     pointer to initialized memcached_st struct

       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.
