KVM_NLIST(3) FreeBSD Library Functions Manual KVM_NLIST(3)
NAME
kvm_nlist - retrieve symbol table names from a kernel image
LIBRARY
Kernel Data Access Library (libkvm, -lkvm)
SYNOPSIS
#include <kvm.h>
#include <nlist.h>
int
kvm_nlist(kvm_t *kd, struct nlist *nl);
DESCRIPTION
kvm_nlist() retrieves the symbol table entries indicated by the name list
argument nl. This argument points to an array of nlist structures,
terminated by an entry whose n_name field is NULL (see nlist(3)). Each
symbol is looked up using the n_name field, and if found, the
corresponding n_type and n_value fields are filled in. These fields are
set to 0 if the symbol is not found.
If kd was created by a call to kvm_open() with a NULL executable image
name, kvm_nlist() will use /dev/ksyms to retrieve the kernel symbol
table.
RETURN VALUES
The kvm_nlist() function returns the number of invalid entries found. If
the kernel symbol table was unreadable, -1 is returned.
FILES
/dev/ksyms
