Subject: ui/ncurses: specify a fixed length for status messages
X-Git-Tag: v1.0.0~166
X-Git-Url: http://git.ozlabs.org/?p=petitboot;a=commitdiff_plain;h=71f338ca02092cb75608a511d6885affaf7adb66;hp=49367fdd5034a010a3f7f657f8ad205ebf9a01fe

ui/ncurses: specify a fixed length for status messages

Incoming status messages can be an arbitrary length; if so, the status
line may be corrupt.

This change uses the 'n' variant of mvwaddnstr(), so we only write one
line of characters.
