KVM_NLIST(3KVM)KVM_NLIST(3KVM)NAMEkvm_nlist - get entries from kernel symbol table
SYNOPSIS
cc [ flag... ] file... -lkvm [ library...]
#include <kvm.h>
#include <nlist.h>
int kvm_nlist(kvm_t *kd, struct nlist *nl);
DESCRIPTION
The kvm_nlist() function examines the symbol table from the kernel
image identified by kd (see kvm_open(3KVM)) and selectively extracts a
list of values and puts them in the array of nlist structures pointed
to by nl. The name list pointed to by nl consists of an array of struc‐
tures containing names, types and values. The n_name field of each
such structure is taken to be a pointer to a character string repre‐
senting a symbol name. The list is terminated by an entry with a null
pointer (or a pointer to a null string) in the n_name field. For each
entry in nl, if the named symbol is present in the kernel symbol table,
its value and type are placed in the n_value and n_type fields. If a
symbol cannot be located, the corresponding n_type field of nl is set
to 0.
RETURN VALUES
The kvm_nlist() functions returns the value of nlist(3UCB) or
nlist(3ELF), depending on the library used.
