73 libmemcached(3) allows you to specify your own memory allocators optimized
76 memcached_set_memory_allocators() is used to set the memory allocators used
77 by the memcached instance specified by ptr. Please note that you cannot
78 override only one of the memory allocators, you have to specify a complete
79 new set if you want to override one of them. All of the memory allocation
80 functions should behave as specified in the C99 standard. Specify NULL as
81 all functions to reset them to the default values.
83 memcached_get_memory_allocators() is used to get the currently used memory
84 allocators by a mamcached handle.
86 memcached_get_memory_allocators_context() returns the void \* that was
87 passed in during the call to memcached_set_memory_allocators().
89 The first argument to the memory allocator functions is a pointer to a
90 memcached structure, the is passed as const and you will need to clone
91 it in order to make use of any operation which would modify it.
99 In version 0.38 all functions were modified to have a context void pointer
100 passed to them. This was so that customer allocators could have their
101 own space for memory.
109 memcached_set_memory_allocators() return MEMCACHED_SUCCESS upon success,
110 and MEMCACHED_FAILURE if you don't pass a complete set of function pointers.
