KVM_NLIST(3)               BSD Programmer's Manual                KVM_NLIST(3)

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, 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.

     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.
