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.
