结构体
| 结构体名称 | 描述 |
|---|---|
| OH_NativeBuffer_Config | OH_NativeBuffer的属性配置，用于申请新的OH_NativeBuffer实例或查询现有实例的相关属性。 |
函数
| 函数名称 | 描述 |
|---|---|
| OH_NativeBuffer_Alloc (const OH_NativeBuffer_Config *config) | 通过OH_NativeBuffer_Config创建OH_NativeBuffer实例，每次调用都会产生一个新的OH_NativeBuffer实例。 |
| OH_NativeBuffer_Reference (OH_NativeBuffer *buffer) | 将OH_NativeBuffer对象的引用计数加1。 |
| OH_NativeBuffer_Unreference (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。 |
| OH_NativeBuffer_GetConfig (OH_NativeBuffer *buffer, OH_NativeBuffer_Config *config) | 用于获取OH_NativeBuffer的属性。 |
| OH_NativeBuffer_Map (OH_NativeBuffer *buffer, void **virAddr) | 将OH_NativeBuffer对应的ION内存映射到进程空间。 |
| OH_NativeBuffer_Unmap (OH_NativeBuffer *buffer) | 将OH_NativeBuffer对应的ION内存从进程空间移除。 |
| OH_NativeBuffer_GetSeqNum (OH_NativeBuffer *buffer) | 获取OH_NativeBuffer的序列号。 |
