NAME
kvm_nlist
—
retrieve symbol table names from a
kernel image
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.
The program
kvm_mkdb(8) builds a database from the running kernel's namelist. If
the database matches the opened kernel,
kvm_nlist
()
uses it to speed lookups.
RETURN VALUES
The kvm_nlist
() function returns the
number of invalid entries found. If the kernel symbol table was unreadable,
-1 is returned.
