54 libmemcached(3) allows you to specify your own memory allocators
55 optimized for your application.
56
57 memcached_set_memory_allocators() is used to set the memory allocators
58 used by the memcached instance specified by ptr. Please note that you
59 cannot override only one of the memory allocators, you have to specify
60 a complete new set if you want to override one of them. All of the
61 memory allocation functions should behave as specified in the C99
62 standard. Specify NULL as all functions to reset them to the default
63 values.
64
65 memcached_get_memory_allocators() is used to get the currently used
66 memory allocators by a mamcached handle.
67
68 memcached_get_memory_allocators_context() returns the void * that was
69 passed in during the call to memcached_set_memory_allocators().
70
71 The first argument to the memory allocator functions is a pointer to a
72 memcached structure, the is passed as const and you will need to clone
73 it in order to make use of any operation which would modify it.
74
76 In version 0.38 all functions were modified to have a context void
77 pointer passed to them. This was so that customer allocators could have
78 their own space for memory.
79
81 memcached_set_memory_allocators() return MEMCACHED_SUCCESS upon
82 success, and MEMCACHED_FAILURE if you don't pass a complete set of
83 function pointers.
