mruby-tlsf uses TLSF memory allocator written by Matthew Conte as a custom allocator in mruby.
This mrbgem defines mrb_state* mrb_open_tlsf(void *mem, size_t bytes).
You can use this instead of mrb_open().
TLSF::available_memory: returns available memory.TLSF::used_memory: returns used memory.TLSF::total_memory: returns total memory.
