hi group
I want to read the volume of the mixer device with a ruby script.
Can anybody tell me what the ruby equivalent is of what the MIXER_READ
macro does in C?
#define SOUND_MIXER_VOLUME 0
#define SOUND_MIXER_READ_VOLUME MIXER_READ(SOUND_MIXER_VOLUME)
#define MIXER_READ(dev) _SIOR('M', dev, int)
I've been googling with keywords like 'ioctl, MIXER_READ SOUND_MIXER',
but with little result. Hopefully someone can me push me in the right
direction...
thanks in advance,
Ruud
