Summary
Functions
| Function | Description |
|---|---|
| OH_NativeWindow_CreateNativeWindowFromSurface (void *pSurface) | struct NativeWindow * 创建NativeWindow实例，每次调用都会产生一个新的NativeWindow实例 |
| OH_NativeWindow_DestroyNativeWindow (struct NativeWindow *window) | void 将NativeWindow对象的引用计数减1，当引用计数为0的时候，该NativeWindow对象会被析构掉 |
| OH_NativeWindow_CreateNativeWindowBufferFromSurfaceBuffer (void *pSurfaceBuffer) | struct NativeWindowBuffer * 创建NativeWindowBuffer实例，每次调用都会产生一个新的NativeWindowBuffer实例 |
| OH_NativeWindow_DestroyNativeWindowBuffer (struct NativeWindowBuffer *buffer) | void 将NativeWindowBuffer对象的引用计数减1，当引用计数为0的时候，该NativeWindowBuffer对象会被析构掉 |
| OH_NativeWindow_NativeWindowRequestBuffer (struct NativeWindow *window, struct NativeWindowBuffer **buffer, int *fenceFd) | int32_t 通过NativeWindow对象申请一块NativeWindowBuffer，用以内容生产 |
| OH_NativeWindow_NativeWindowFlushBuffer (struct NativeWindow *window, struct NativeWindowBuffer *buffer, int fenceFd, Region region) | int32_t 通过NativeWindow将生产好内容的NativeWindowBuffer放回到Buffer队列中，用以内容消费 |
| OH_NativeWindow_NativeWindowCancelBuffer (struct NativeWindow *window, struct NativeWindowBuffer *buffer) | int32_t 通过NativeWindow将之前申请出来的NativeWindowBuffer返还到Buffer队列中，供下次再申请 |
| OH_NativeWindow_NativeWindowHandleOpt (struct NativeWindow *window, int code,...) | int32_t 设置/获取NativeWindow的属性，包括设置/获取宽高、内容格式等 |
| OH_NativeWindow_GetBufferHandleFromNative (struct NativeWindowBuffer *buffer) | BufferHandle * 通过NativeWindowBuffer获取该buffer的BufferHandle指针 |
| OH_NativeWindow_NativeObjectReference (void *obj) | int32_t 增加一个NativeObject的引用计数 |
| OH_NativeWindow_NativeObjectUnreference (void *obj) | int32_t 减少一个NativeObject的引用计数，当引用计数减少为0时，该NativeObject将被析构掉 |
| OH_NativeWindow_GetNativeObjectMagic (void *obj) | int32_t 获取NativeObject的MagicId |
