| 函数名称 | 描述 |
| -------- | -------- |
| [OH_NativeWindow_CreateNativeWindow]( _native_window.md#oh_nativewindow_createnativewindow) (void \*pSurface) | 创建NativeWindow实例，每次调用都会产生一个新的NativeWindow实例 |
| [OH_NativeWindow_DestroyNativeWindow]( _native_window.md#oh_nativewindow_destroynativewindow) (OHNativeWindow \*window) | 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]( _native_window.md#oh_nativewindow_createnativewindowbufferfromsurfacebuffer) (void \*pSurfaceBuffer) | 创建NativeWindowBuffer实例，每次调用都会产生一个新的NativeWindowBuffer实例 |
| [OH_NativeWindow_DestroyNativeWindowBuffer]( _native_window.md#oh_nativewindow_destroynativewindowbuffer) (OHNativeWindowBuffer \*buffer) | 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]( _native_window.md#oh_nativewindow_nativewindowrequestbuffer) (OHNativeWindow \*window, OHNativeWindowBuffer \*\*buffer, int \*fenceFd) | 通过NativeWindow对象申请一块NativeWindowBuffer，用以内容生产 |
| [OH_NativeWindow_NativeWindowFlushBuffer]( _native_window.md#oh_nativewindow_nativewindowflushbuffer) (OHNativeWindow \*window, OHNativeWindowBuffer \*buffer, int fenceFd, [Region](_region.md) region) | 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_NativeWindowAbortBuffer]( _native_window.md#oh_nativewindow_nativewindowabortbuffer) (OHNativeWindow \*window, OHNativeWindowBuffer \*buffer) | 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]( _native_window.md#oh_nativewindow_nativewindowhandleopt) (OHNativeWindow \*window, int code,...) | 设置/获取NativeWindow的属性，包括设置/获取宽高、内容格式等 |
| [OH_NativeWindow_GetBufferHandleFromNative]( _native_window.md#oh_nativewindow_getbufferhandlefromnative) (OHNativeWindowBuffer \*buffer) | 通过NativeWindowBuffer获取该buffer的BufferHandle指针 |
| [OH_NativeWindow_NativeObjectReference]( _native_window.md#oh_nativewindow_nativeobjectreference) (void \*obj) | 增加一个NativeObject的引用计数 |
| [OH_NativeWindow_NativeObjectUnreference]( _native_window.md#oh_nativewindow_nativeobjectunreference) (void \*obj) | 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]( _native_window.md#oh_nativewindow_getnativeobjectmagic) (void \*obj) | 获取NativeObject的MagicId |
| [OH_NativeWindow_NativeWindowSetScalingMode]( _native_window.md#oh_nativewindow_nativewindowsetscalingmode) (OHNativeWindow \*window, uint32_t sequence, [OHScalingMode]( _native_window.md#ohscalingmode) scalingMode) | 设置NativeWindow的ScalingMode |
| [OH_NativeWindow_NativeWindowSetMetaData]( _native_window.md#oh_nativewindow_nativewindowsetmetadata) (OHNativeWindow \*window, uint32_t sequence, int32_t size, const [OHHDRMetaData](_o_h_h_d_r_meta_data.md) \*metaData) | 设置NativeWindow的元数据 |
| [OH_NativeWindow_NativeWindowSetMetaDataSet]( _native_window.md#oh_nativewindow_nativewindowsetmetadataset) (OHNativeWindow \*window, uint32_t sequence, [OHHDRMetadataKey]( _native_window.md#ohhdrmetadatakey) key, int32_t size, const uint8_t \*metaData) | 设置NativeWindow的元数据集。 |
| [OH_NativeWindow_NativeWindowSetTunnelHandle]( _native_window.md#oh_nativewindow_nativewindowsettunnelhandle) (OHNativeWindow \*window, const [OHExtDataHandle](_o_h_ext_data_handle.md) \*handle) | 设置NativeWindow的TunnelHandle。 |
