Function SDL_GetAudioStreamGain

pub unsafe extern "C" fn SDL_GetAudioStreamGain(
    stream: *mut SDL_AudioStream,
) -> f32

Available on crate feature dep_sdl3 only.

Get the gain of an audio stream.

The gain of a stream is its volume; a larger gain means a louder output, with a gain of zero being silence.

Audio streams default to a gain of 1.0f (no change in output).

Parameters

• stream: the SDL_AudioStream to query.

Return value

Returns the gain of the stream or -1.0f on failure; call SDL_GetError() for more information.

Thread safety

It is safe to call this function from any thread, as it holds a stream-specific mutex while running.

Availability

This function is available since SDL 3.2.0.
