Branch: MAIN
CVS Tags: OPENBSD_7_5_BASE, OPENBSD_7_5, OPENBSD_7_4_BASE, OPENBSD_7_4, HEAD
Changes since 1.234: +3 -1 lines
Add sysctl hw.ucomnames to list 'fixed' paths to USB serial
ports.
Suggested by deraadt@, USB route idea from kettenis@. Feedback
from anton@, man page improvements from deraadt@, jmc@,
schwarze@.

/*
* Macros for filling in the bulk of a kinfo_proc structure, used
* in the kernel to implement the KERN_PROC sysctl and in userland
* in libkvm to implement reading from kernel crashes. The macro
* arguments are all pointers; by name they are:
* kp - target kinfo_proc structure
* copy_str - a function or macro invoked as copy_str(dst,src,maxlen)
* that has strlcpy or memcpy semantics; the destination is
* pre-filled with zeros; for libkvm, src is a kvm address
* p - source struct proc
* pr - source struct process
* uc - source struct ucreds
* pg - source struct pgrp
* paddr - kernel address of the source struct proc
* praddr - kernel address of the source struct process
* sess - source struct session
* vm - source struct vmspace
* lim - source struct plimits
* sa - source struct sigacts
* There are some members that are not handled by these macros
* because they're too painful to generalize: p_ppid, p_sid, p_tdev,
* p_tpgid, p_tsess, p_vm_rssize, p_u[us]time_{sec,usec}, p_cpuid
