NAME
kvm_nlist —
retrieve symbol table names from a
kernel image
LIBRARY
library “libkvm”
SYNOPSIS
#include
<sys/types.h>
#include <kvm.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.
kldsym(2) 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.
