Functions

• OH_NativeWindow_CreateNativeWindow^⚠
  @brief Creates a OHNativeWindow instance. A new OHNativeWindow instance is created each time this function is called.
• OH_NativeWindow_CreateNativeWindowBufferFromSurfaceBuffer^⚠
  @brief Creates a OHNativeWindowBuffer instance. A new OHNativeWindowBuffer instance is created each time this function is called.
• OH_NativeWindow_DestroyNativeWindow^⚠
  @brief Decreases the reference count of a OHNativeWindow instance by 1, and when the reference count reaches 0, destroys the instance.
• OH_NativeWindow_DestroyNativeWindowBuffer^⚠
  @brief Decreases the reference count of a OHNativeWindowBuffer instance by 1 and, when the reference count reaches 0, destroys the instance.
• OH_NativeWindow_GetBufferHandleFromNative^⚠
