KVM_KERNDISP(3) FreeBSD Library Functions Manual KVM_KERNDISP(3)
NAME
kvm_kerndisp - get kernel displacement
LIBRARY
Kernel Data Access Library (libkvm, -lkvm)
SYNOPSIS
#include <kvm.h>
kssize_t
kvm_kerndisp(kvm_t *kd);
DESCRIPTION
kvm_kerndisp() returns the number of bytes by which the kernel referenced
by kd is displaced. This is the difference between the kernel's base
virtual address at run time and the kernel base virtual address specified
in the kernel image file.
Note that if the kernel is moved to a lower memory address, the
displacement will be negative.
RETURN VALUES
kvm_kerndisp() returns the number of bytes by which the kernel is
displaced. If the kernel is not displaced or if it is not possible to
find the displacement then 0 is returned.
