=head1 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.

The first argument to the memory allocator functions is a pointer to a
memcached structure, and you may use the memcached_set_user_data() and
memcached_get_user_data() to store a user-specific value to each memcached
structure.

=head1 RETURN

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