.Sh NAME

.Nm kvm_nlist
|
|
.Nd retrieve symbol table names from a kernel image
|
|
.Sh SYNOPSIS
|
|
.Fd #include <kvm.h>
|
|
.Fd #include <nlist.h>
|
|
.Ft int
|
|
.Fn kvm_nlist "kvm_t *kd" "struct nlist *nl"
|
|
.Sh DESCRIPTION
|
|
.Fn kvm_nlist
|
|
retrieves the symbol table entries indicated by the name list argument
|
|
.Fa \&nl .
|
|
This argument points to an array of nlist structures, terminated by
|
|
an entry whose n_name field is
|
|
.Dv NULL
|
|
(see
|
|
.Xr 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.
|
|
.Pp
|
|
The program
|
|
.Xr kvm_mkdb 8
|
|
builds a database from the running kernel's namelist.
|
|
If the database matches the opened kernel,
|
|
.Fn kvm_nlist
|
|
uses it to speed lookups.
|
|
.Sh RETURN VALUES
|
|
The
|
|
.Fn kvm_nlist
|
|
function returns the number of invalid entries found.
|
|
If the kernel symbol table was unreadable, -1 is returned.
