H A Dnative-buffer-guidelines.md1 # NativeBuffer开发指导 (C/C++)
5 NativeBuffer是提供**共享内存**的模块。开发者可以通过`NativeBuffer`接口实现共享内存的申请、使用、属性查询、释放等操作。
6 针对NativeBuffer，常见的开发场景如下：
8 * 通过`NativeBuffer`提供的Native API接口申请`OH_NativeBuffer`实例，获取内存的属性信息，把对应的ION内存映射到进程空间。
16 …eference (OH_NativeBuffer \*buffer) | 将OH_NativeBuffer对象的引用计数减1，当引用计数为0的时候，该NativeBuffer对象会被析构掉。 |
26 以下步骤描述了如何使用`NativeBuffer`提供的Native API接口，创建`OH_NativeBuffer`实例获取内存的属性信息，并把对应的ION内存映射到进程空间。
