25 DESCRIPTION
26 -----------
27
28 :c:func:`memcached_create()` is used to create a :c:type:`memcached_st`
29 structure that will then be used by other libmemcached(3) functions to
30 communicate with the server. You should either pass a statically declared
31 :c:type:`memcached_st` to :c:func:`memcached_create()` or
32 a NULL. If a NULL passed in then a structure is allocated for you.
33
34 Please note, when you write new application use
35 :c:func:`memcached_create_with_options()` over
36 :c:func:`memcached_create()`.
37
38 :c:func:`memcached_clone()` is similar to :c:func:`memcached_create()` but
39 it copies the defaults and list of servers from the source
40 :c:type:`memcached_st`. If you pass a null as the argument for the source
41 to clone, it is the same as a call to :c:func:`memcached_create()`.
42 If the destination argument is NULL a :c:type:`memcached_st` will be allocated
43 for you.
44
45 :c:func:`memcached_servers_reset()` allows you to zero out the list of
46 servers that the :c:type:`memcached_st` has.
47
48 To clean up memory associated with a :c:type:`memcached_st` structure you
49 should pass it to :c:func:`memcached_free()` when you are finished using it.
50 :c:func:`memcached_free()` is the only way to make sure all memory is
51 deallocated when you finish using the structure.
52
53 You may wish to avoid using memcached_create(3) or memcached_clone(3) with a
54 stack based allocation. The most common issues related to ABI safety involve
55 heap allocated structures.

59 RETURN
60 ------
61
62
63 :c:func:`memcached_create()` returns a pointer to the :c:type:`memcached_st`
64 that was created (or initialized). On an allocation failure, it returns NULL.
65
66 :c:func:`memcached_clone()` returns a pointer to the :c:type:`memcached_st`
67 that was created (or initialized). On an allocation failure, it returns NULL.
