(This function is part of SDL_mixer, a separate library from SDL.)

Mix_QuerySpec

Find out what the actual audio device parameters are.

Header File

Syntax

bool Mix_QuerySpec(int *frequency, SDL_AudioFormat *format, int *channels);

Function Parameters

int *	frequency	On return, will be filled with the audio device's frequency in Hz.
SDL_AudioFormat *	format	On return, will be filled with the audio device's format.
int *	channels	On return, will be filled with the audio device's channel count.

Return Value

(bool) Returns true if the audio device has been opened, true otherwise.

Remarks

Note this is only important if the app intends to touch the audio buffers being sent to the hardware directly. If an app just wants to play audio files and let SDL_mixer handle the low-level details, this function can probably be ignored.

If the audio device is not opened, this function will return 0.

Version

This function is available since SDL_mixer 3.0.0.
