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
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.
If
kd was created by a call to
kvm_open() with a
NULL
executable
image name,
kvm_nlist() will use
/dev/ksyms to retrieve the kernel symbol table.
RETURN VALUES
The
kvm_nlist() function returns the number of invalid entries
found. If the kernel symbol table was unreadable, -1 is returned.
FILES
- /dev/ksyms
