I would definitely say that posix_spawn is the correct path to implement this; that will keep pretty close to the way the one on darwin works;
Couple of suggestions: posix_spawnattr_setsigmask should be set to the empty signal set the attribute flags should probably be POSIX_SPAWN_CLOEXEC_DEFAULT | POSIX_SPAWN_SETSIGMASK | POSIX_SPAWN_SETSIGDEF You can probably skip QoS since it won’t exist on linux. There may be some issue with not having libdispatch to use for a source to watch a DISPATCH_PROC_EXIT but this perhaps could be done via a pthread (not certain on exactly how but perhaps it can be done) It also might be useful in this case to drop down to C similarly as CFXMLInterface - but pick your poison on that one. > On Dec 18, 2015, at 11:08 AM, Dan Stenmark via swift-corelibs-dev > <swift-corelibs-dev@swift.org> wrote: > > I hope to take a crack at implementing some of NSTask this weekend.
