[Spice-devel] [spice-gtk v1 1/4] spice-channel: Properly error out if reconnect fails

[Victor Toso]

From: Victor Toso <me at victortoso.com>

The channel_connect() function could fail leading to a spice-channel
existing as zombie (its coroutine return soon after).

Check if channel_connect() fails and give a proper error signal to
user when that happens.
