    void* context = nullptr
    );

##### Return Values

The function returns `false` if it was not possible to send the request, or `true` otherwise. If the request was sent but failed, the specified callback will be invoked with an appropriate error code.

 

##### Example

Subscribe to camera status updates:

``` wasm
fsCameraSubscribeToStatusUpdate(CameraGetStatusCallback);
```

 

User defined callback:

``` wasm
void CameraGetStatusCallback(FsCameraEvent event, const FsAcquiredState acquiredState, const bool gameControlled, void* ctx)
{
    if (event == FS_CAMERA_EVENT_STATUS_CHANGED)
    {
        // cameraParam is a user defined struct to store camera informations
        cameraParam.acquiredState = acquiredState;
        cameraParam.gameControlled = gameControlled;
    }
}
```
