SYNOPSIS

#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 structures containing names, types and values. The
n_name field
of each such structure is taken to be a pointer to a character string
representing 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(3ELF).
