  34 =head1 DESCRIPTION
  35
  36 libmemcached(3) allows you to specify your own memory allocators optimized
  37 for your application.
  38
  39 memcached_set_memory_allocators() is used to set the memory allocators used
  40 by the memcached instance specified by ptr. Please note that you cannot
  41 override only one of the memory allocators, you have to specify a complete
  42 new set if you want to override one of them. All of the memory allocation
  43 functions should behave as specified in the C99 standard. Specify NULL as
  44 all functions to reset them to the default values.
  45
  46 memcached_get_memory_allocators() is used to get the currently used memory
  47 allocators by a mamcached handle.
  48
  49 =head1 RETURN
  50
  51 memcached_set_memory_allocators() return MEMCACHED_SUCCESS upon success,
  52 and MEMCACHED_FAILURE if you don't pass a complete set of function pointers.
