allocator类用于自定义底层内存的分配: template<typenameT>classMyAllocator{public:usingvalue_type = T;usingpointer = T*;MyAllocator() =default;template<typenameU>MyAllocator(constMyAllocator<U>&){}pointerallocate(std::size_tn){returnstatic_cast<pointer>(operatornew(n *sizeof(T))); }voiddeallocat...
intback(){returnb;} }; 如上进行,两个派生类在基类的基础上进行继承并重写了虚函数,下面使用clang也就是llvm编译器来进行结构展示,执行命令clang -Xclang -fdump-record-layouts -c test.cpp > layout查看内存布局: *** Dumping AST Record Layout 0|classBase 0| (Base vftable pointer) 8|inta | [siz...
function main(){ var soBase = Module.findBaseAddress("libd3mug.so"); const update = new NativeFunction(soBase.add(0x0000780), "pointer", ["char"]); const instance = soBase.add(0x02D18); instance.writePointer(new NativePointer(0)); for (const t of hitpoints) { update(t); } conso...
insert(std::make_unique<Derived>()); UniquePointerSet<Base> destination; destination.insert(begin(source), end(source)); 但是会出错: error: use of deleted function 'std::unique_ptr<_Tp, _Dp>::unique_ptr(const std::unique_ptr<_Tp, _Dp>&) [with _Tp = Base; _Dp = std::default...
BindNativeFunction(engine, *object, "createModuleContext", moduleName, JsBaseContext::CreateModuleContext); return objValue; } 接下来,继续分析一下x19 需要加上#8的原因。下面3条指令是调用 GetHandleAddr(const EcmaVM *vm, uintptr_t localAddress) 方法,这样对应起来[x19, #8]保存的应该是address。
// I’ve omitted the function pointer code. float _return_value = _il2cpp_pinvoke_func(___v); return _return_value; 同样的,参数是按值传递的,就像上面那个int的例子一样。如果我们想改变Vector的值,我们必须按引用传递这个变量,就像下面SetX函数(HelloWorld_SetX_m6)所做的那样: ...

This function is invoked before the main function as a part of process initialization. The return address is another type of code pointer. To protect return addresses from leakage, the compiler extension needs to instrument instructions to copy return addresses to CPP pages and remove their value ...
