DESCRIPTION
libmemcached(3) allows you to specify your own memory allocators, opti-
mized 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 mem-
ory allocation functions should behave as specified in the C99 stan-
dard. Specify NULL as all functions to reset them to the default val-
ues.
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 suc-
cess, and MEMCACHED_FAILURE if you don't pass a complete set of func-
tion pointers.
