The /proc equivalent in OpenBSD is ptrace(2).
- Retr0id 3y agoCould you elaborate? To me there seems extremely little overlap there (I'm familiar with both the procfs and linux's ptrace APIs, but not OpenBSD's ptrace).
- dun44 3y agoPtrace could an equivalent of what /proc was originally supposed to be, before it got repurposed for a bunch of sysctl-like purposes.
- Retr0id 3y agoInteresting. I didn't know much about /proc's original design intent, and Wikipedia indeed says "the design of procfs aimed to replace the ptrace system call used for process tracing", citing https://lucasvr.gobolinux.org/etc/Killian84-Procfs-USENIX.pdf https://lucasvr.gobolinux.org/etc/Killian84-Procfs-USENIX.pd...
