[alsa-devel] Help in understanding SND_PCM_TSTAMP_ENABLE mode snd_pcm_htimestamp function

Hi,

I am looking for a method to maintain timestamps for every sample read or written. I noticed the *SND_PCM_TSTAMP_ENABLE mode. But the description mentions - "" *pdate timestamp at every hardware position update" Doe this mean that the when snd_pcm_htimestamp() is issued, we will get the last hardware update timestamp or does it mean that it will fetch the timestamp of that particular sample?

Thanks, Divya
