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.
