Question about snd_pcm_sw_params_get_boundary

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

snd_pcm_uframes_t boundary;
snd_pcm_sw_params_get_boundary(params, &boundary); 

I see a huge number like "7944349742681554944" in boundary after this call.
Is this normal?

I see exactly the same huge number when I use this boundary to set the
threshold as in the following code part:

snd_pcm_sw_params_set_stop_threshold(handlePlayback, params, boundary);
snd_pcm_sw_params_get_stop_threshold(params, &threshold);

So the returning threshold value is again "7944349742681554944".

Can you comment on the correctness of these values?
