DESCRIPTION

       libmemcached(3) allows you to specify your own memory allocators
       optimized for your application.

       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.
