From bb4f468b73c8a888bec1e5b2ba7f1575ab7f8456 Mon Sep 17 00:00:00 2001 From: user Date: Thu, 16 Jul 2026 11:15:12 +0200 Subject: jobs: background execution (&), non-blocking reap, spin demo - sys_reap: nohang reap of a finished zombie child (-> pid or 0). - shell: 'cmd &' launches in the background (prints [pid], no wait); reaps finished jobs at the prompt ([pid done]). Foreground now waits for its own child specifically (loops wait(), reporting bg completions meanwhile) so kill reports the right pid. - spin: a process that yields forever - a target for ps/kill. - verified: spin &; ps shows it; kill removes just that one; immortal init; self-finishing bg worker reaped with [pid done]. --- c/spin.c | 6 ++++++ 1 file changed, 6 insertions(+) create mode 100644 c/spin.c (limited to 'c/spin.c') diff --git a/c/spin.c b/c/spin.c new file mode 100644 index 0000000..2a3d4e8 --- /dev/null +++ b/c/spin.c @@ -0,0 +1,6 @@ +#include "gbos.h" +/* spin: a harmless long-running process that just yields forever. + Useful as a target for `ps` and `kill`. */ +void main(void) { + for (;;) yield(); +} -- cgit v1.3.1-sl0p
