# CAMERA_SwitchOffLED*

## Syntax

  `#include <twl/camera.h>`
  `CAMERAResult CAMERA_SwitchOffLED(void);`
  `CAMERAResult CAMERA_SwitchOffLEDAsync(CAMERACallback callback, void *arg);`

## Arguments

callback | Function that is called when asynchronous processing has completed.
arg | Arguments when the callback function is invoked.

## Return Values

Returns `CAMERA_RESULT_SUCCESS` if configuration was successful.

## Description

Turns off the outer camera LED for the duration of a single blink.
The outer camera LED is configured to be lit when the outer camera is active. By calling this function from that state, the outer camera LED will be turned off for the duration of a single blink, as configured by the `CAMERA_SetLED` function. Note that this will consequently fail if the outer camera is not active.
This function has the same behavior as running `CAMERA_SetLED(TRUE)` and `CAMERA_SetLED(FALSE)` in succession.
