kvm_nlist —
retrieve symbol table names from a kernel image
#include <kvm.h>
#include <nlist.h>
int
kvm_nlist(kvm_t
*kd, struct nlist
*nl);
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.
The kvm_nlist() function returns the
number of invalid entries found. If the kernel symbol table was unreadable,
-1 is returned.
