SDL_AUDIO_DEVICE_DEFAULT_RECORDING(3) SDL3 FUNCTIONS SDL_AUDIO_DEVICE_DEFAULT_RECORDING(3)

SDL_AUDIO_DEVICE_DEFAULT_RECORDING - A value used to request a default recording audio device.

Defined in SDL3/SDL_audio.h

#include "SDL3/SDL.h"
#define SDL_AUDIO_DEVICE_DEFAULT_RECORDING ((SDL_AudioDeviceID) 0xFFFFFFFEu)

Several functions that require an SDL_AudioDeviceID

will accept this value to signify the app just wants the system to choose a default device instead of the app providing a specific one.

This macro is available since SDL 3.2.0.
