KVM_NLIST(3)						   BSD 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.
