KVM_NLIST(3)            NetBSD 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
kvm_nlist() retrieves the symbol table entries indicated by the name list argument nl. This argument points to an array of nlist structures, ter- minated by an entry whose n_name field is NULL (see nlist(3)). Each sym- bol 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 ta- ble.
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
