Subject: Windows: handle SIGBREAK.
X-Git-Tag: fio-2.0.10~1
X-Git-Url: https://git.kernel.dk/?p=fio.git;a=commitdiff_plain;h=2f694507513e44e59139f57f28e08c5d0772880e

Windows: handle SIGBREAK.

The only way to send a POSIX-style signal from another application on Windows
is to use GenerateConsoleCtrlEvent with either CTRL_C_EVENT or
CTRL_BREAK_EVENT. CTRL_BREAK_EVENT is the only one which gets through to
applications, so add a signal handler for it to allow fio to quit cleanly.
