getGain method

double getGain()

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).

\param stream the SDL_AudioStream to query. \returns the gain of the stream or -1.0f on failure; call SDL_GetError() for more information.

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

\since This function is available since SDL 3.1.3.
