Subject: Any issues with GETOSPACE OSS ioctl?
Date: Wed, 05 Nov 2008 09:41:16 -0600	[thread overview]
Message-ID: <4911BE9C.8010607@freescale.com> (raw)

I have a customer who reports that when his OSS application makes several
write() followed by SNDCTL_DSP_GETOSPACE, the returned value is not decreasing,
which implies that the write() commands are not going through.

I've looked at the OSS documentation for this ioctl
(http://manuals.opensound.com/developer/SNDCTL_DSP_GETOSPACE.html), and it
implies that it is not reliable.  But since the customer is using ALSA (i.e.
ALSA's OSS emulation), I don't know if that applies.

So I'd like to know how the 'bytes' return value is calculate in ALSA.
