memsize_of_m(VALUE self, VALUE obj)
{
return SIZET2NUM(rb_obj_memsize_of(obj));
}
Return consuming memory size of obj in bytes.
Note that the return size is incomplete. You need to deal with this information as only a HINT. Especially, the size of T_DATA may not be correct.
This method is only expected to work with C Ruby.
From Ruby 2.2, memsize_of(obj) returns a memory size includes sizeof(RVALUE).
