[alsa-devel] [PATCH] aplay: Fix error message when writing captured data

[Daniel Baluta]

Write can return less then requested bytes, but we treat
this as an error.

Anyhow, errno is not updated in this case and we can end
up with a confusing error message.

For example, when there is no room to write data into the
output file we receive:

$ arecord -d 2000 -c 2 -r 192000 -f S16_LE -Dplughw:0,0 audio.wav
Recording WAVE '/mnt/msc/audio.wav' : Signed 16 bit Little Endian, Rate
192000 Hz, Stereo
audio.wav: No such file or directory
