# CARD_CancelBackupAsync

## Syntax

  `#include <nitro/card.h>`
  `void CARD_CancelBackupAsync(void);`

## Arguments

None.

## Return Values

None.

## Description

If an asynchronous process for the card backup device is executing, it requests cancellation of the process. Regardless of whether there is an executing asynchronous process or not, the function immediately returns control.
The result of the cancelled process is `CARD_RESULT_CANCELED`.
Note that a call of this function is not reflected immediately because cancel requests are determined periodically inside of the asynchronous process.
