Yes, the double negate is a little trick to give you either a 1 or a 0 instead of the value of the operation. -Original Message- From: Ros-dev [mailto:ros-dev-boun...@reactos.org] On Behalf Of Pierre Schweitzer Sent: 16 June 2014 07:31 To: ros-dev@reactos.org Subject: Re: [ros-dev] [ros-diffs] [hbelusca] 63599: [TASKMGR]: Use the EndTask API to kill tasks.

It's equivalent to writing something != 0, although less readable. I have no idea if compilers actually generate better code for it, or people just do it because it's shorter to type.

+1 @ Ged, yes I prefer having a 1 or 0 instead of something else (in case somebody after makes a “ForceEndTask == TRUE” comparison instead of just checking for non-zero value of ForceEndTask). H.
