Subject: Define channel map position enum in pcm.h
X-Git-Tag: v1.0.27~58
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=915b26bfe8af876d467a37c336c6bf22d5e370fe;p=alsa-lib.git

Define channel map position enum in pcm.h

The original definition is in sound/asound.h, but we need to export to
alsa-lib users, too.
