[PATCH 00/15] alsa-gobject: seq: enhancement for error reporting

[GitHub pull_request - opened]

alsa-project/alsa-gobject pull request #50 was opened from takaswie:

The patchset is the 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 ALSASeq.UserClient.
The error domain delivers information about the cause of error.

```
Takashi Sakamoto (15):
  seq: skip check of return value from g_malloc()
  seq: check whether method argument for GError is available
  seq: add checks for method arguments
  seq: user_client: just return when character device is not opened
  seq: add GLib enumeration to report type of error for ALSASeq.UserClient
  seq: user_client: add GQuark to report error for ALSASeq.UserClient
  seq: user_client: report error for ioctl
  seq: user_client: report open/write error
  seq: user_client: report error for port access permission
  seq: user_client: report error for queue access permission

  seq: obsolete library-wide error quark
