   3 Subject: fix return value of snd_pcm_rewind()/snd_pcm_forward() to return how much actually ...
   4 X-Git-Url: http://git.alsa-project.org/?p=alsa-lib.git;a=commitdiff_plain;h=8d3fb3102f672a7b09be92811e89d49f89c1742b;hp=15769ead725b7c215dedd4ea5196955086d2044a

   6 fix return value of snd_pcm_rewind()/snd_pcm_forward() to return how much actually has been rewound, instead of what actually could have rewound
   7
   8 Make snd_pcm_plugin_rewind()/_forward() actually return how much has
   9 been rewound/forwarded instead of how much could have been
  10 rewounded/forwarded. This makes the code actually do what the
  11 documentation of snd_pcm_rewind() suggests.
