Date: Mon, 20 Nov 2017 16:35:00 -0000 [thread overview]
Message-ID: <1511195683-2055-8-git-send-email-simon.marchi@ericsson.com> (raw)
In-Reply-To: <1511195683-2055-1-git-send-email-simon.marchi@ericsson.com>
From: Simon Marchi <simon.marchi@polymtl.ca>
Replace with for_each_thread with pid filtering.
gdb/gdbserver/ChangeLog:
* linux-low.c (linux_detach_lwp_callback): Return void, remove
args parameter, don't check for pid.
(linux_detach): Use for_each_thread.
