## RETURN VALUE

( **SDL\_AudioDeviceID**\
  \*) Returns a 0 terminated array of device instance IDs or NULL on error; call  **SDL\_GetError** () for more information. This should be freed with  **SDL\_free** () when it is no longer needed.

## THREAD SAFETY

It is safe to call this function from any thread.

## AVAILABILITY

This function is available since SDL 3.2.0.
