       memcached_free_fn mem_free, memcached_realloc_fn mem_realloc, memcached_calloc_fn mem_calloc,
       void *context)

       void memcached_get_memory_allocators(memcached_st *ptr, memcached_malloc_fn *mem_malloc,
       memcached_free_fn *mem_free, memcached_realloc_fn *mem_realloc, memcached_calloc_fn *mem_calloc)

       void * memcached_get_memory_allocators_context(const memcached_st *ptr)

       void * (*memcached_malloc_fn)(memcached_st *ptr, const size_t size, void *context)

       void * (*memcached_realloc_fn)(memcached_st *ptr, void *mem, const size_t size, void *context)

       void (*memcached_free_fn)(memcached_st *ptr, void *mem, void *context)

DESCRIPTION

       libmemcached(3)  allows  you  to specify your own memory allocators, optimized for your application. This
       enables libmemcached to be used inside of applications that have their own malloc implementation.

       memcached_set_memory_allocators() is used to set the memory allocators used  by  the  memcached  instance
       specified  by  ptr.  Please  note that you cannot override only one of the memory allocators, you have to
       specify a complete new set if you want to override one of them. All of the  memory  allocation  functions
       should  behave  as  specified  in  the  C99  standard. Specify NULL as all functions to reset them to the
       default values.

       memcached_get_memory_allocators() is used to get the currently used  memory  allocators  by  a  mamcached
       handle.

       memcached_get_memory_allocators_context()  returns  the  void  *  that  was  passed in during the call to
       memcached_set_memory_allocators().

       The first argument to the memory allocator functions is a pointer to a memcached structure, the is passed
       as const and you will need to clone it in order to make use of any operation which would modify it.

NOTES

       In version 0.38 all functions were modified to have a context void pointer passed to them.  This  was  so
       that customer allocators could have their own space for memory.

RETURN

       memcached_set_memory_allocators()  return  MEMCACHED_SUCCESS  upon  success, and MEMCACHED_FAILURE if you
       don't pass a complete set of function pointers.
