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
     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.
