KVM_NLIST(3) FreeBSD Library Functions Manual KVM_NLIST(3)

NAME

kvm_nlistretrieve 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

The kvm_nlist() function 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.

The kldsym(2) system call is used to locate the symbol. This is a less than perfect emulation of the nlist values but has the advantage of being aware of kernel modules and is reasonably fast.

RETURN VALUES

The kvm_nlist() function returns the number of invalid entries found. If the kernel symbol table was unreadable, -1 is returned.
