int Mix_QuerySpec(int *frequency, Uint16 *format, int *channels)

frequency

A pointer to an int where the frequency actually used by the opened audio device will be stored.

Get the actual audio format in use by the opened audio device. This may or may not match the parameters you passed to Mix_OpenAudio.

Returns: 0 on error. If the device was open the number of times it was opened will be returned. The values of the arguments variables are not set on an error.

// get and print the audio format in use int numtimesopened, frequency, channels; Uint16 format; numtimesopened=Mix_QuerySpec(&frequency, &format, &channels); if(!numtimesopened) { printf("Mix_QuerySpec: %s\n",Mix_GetError()); } else { char *format_str="Unknown"; switch(format) { case AUDIO_U8: format_str="U8"; break; case AUDIO_S8: format_str="S8"; break; case AUDIO_U16LSB: format_str="U16LSB"; break; case AUDIO_S16LSB: format_str="S16LSB"; break; case AUDIO_U16MSB: format_str="U16MSB"; break; case AUDIO_S16MSB: format_str="S16MSB"; break; } printf("opened=%d times frequency=%dHz format=%s channels=%d", numtimesopened, frequency, format_str, channels); }
