A pointer to void simply points to a raw memory location. Sometimes it's necessary to use void* pointers, for example when passing between C++ code and C functions.When a typed pointer is cast to a void pointer, the contents of the memory location are unchanged. However, the type ...

Using Imported C Functions in Swift Overview TheUnsafeMutableRawPointertype provides no automated memory management, no type safety, and no alignment guarantees. You are responsible for handling the life cycle of any memory you work with through unsafe pointers, to avoid leaks or undefined behavior....

UnsafeMutableRawPointer 的基本概念 UnsafeMutableRawPointer是一个代表可变内存的原始指针。与其他更安全的指针类型相比,它更接近底层的内存操作,使得开发者能够嵌入 C 语言风格的指针处理方式。 使用UnsafeMutableRawPointer 进行内存操作 以下是一个简单的示例,展示了如何创建一个UnsafeMutableRawPointer,并插入和移位数据...
