[PATCH 00/16] alsa-gobject: timer: enhancement for error reporting

[GitHub pull_request - opened]

alsa-project/alsa-gobject pull request #49 was opened from takaswie:

The patchset is a part of work about #47.

Current implementation uses library-wide error domain to report error. this
is partly against rule of GError usage. Furthermore, the error delivers
information just about errno and hard to know the cause of error.

This patchset enhances error reporting. The library-wide error domain is
obsoleted. A new error domain is added just for ALSATimer.UserInstance.
The error domain delivers information about the cause of error.

```
