Hi everybody, I'm writing a little software that play a tone on a pcm device. In the hw param initialization I'm hardcoding the "periods" and "period_size" values:
unsigned int periods = 4; if (snd_pcm_hw_params_set_periods_near(buzzer_device.pcm_handle, buzzer_device.hwparams, &periods, 0) < 0) { fprintf(stderr, "Error setting periods.\n"); return 1; } ///* set the period time */ period_size = 8192; err = snd_pcm_hw_params_set_period_size_near(buzzer_device.pcm_handle, buzzer_device.hwparams, &period_size, 0); if (err < 0) { printf("Unable to get period size for playback: %s\n", snd_strerror(err)); return err; }
I'd like to read this parameter form the .asoundrc file, so I'm wondering if there were API that does this task.
Thanks
