Subject: [Qemu-devel] Why not use exit() instead of abort()?
Date: Sun, 5 Aug 2007 23:13:55 +0200	[thread overview]
Message-ID: <20070805211355.GA2888@chrom.inf.tu-dresden.de> (raw)

[-- Attachment #1: Type: text/plain, Size: 393 bytes --]

There are a couple of places in qemu, where abort() is called.
The most commonly used one is perhaps cpu_abort() which is called
e.g. when a triple fault occures.

As abort() does not call any atexit() function, cleanup is not
performed. This leaves for example the terminal in a state where
the cursor is invisible.

Are there any reasons not to use exit(1) in cpu_abort()?
